You suspect the company of falsely advertising the beneﬁts of taking their pills. Suppose you take a sample of 100 product users and ﬁnd that only 5% have lost at least 10 pounds. Is this enough to prove your claim? What about if 72% had lost at least 10 pounds? Goal: 9.1 Elements of a Hypothesis Test 1. Assumptions 2. Hypotheses Each hypothesis test has two hypotheses about the population: Null Hypothesis (H0 ): Alternative Hypothesis (Ha ): 1 Stat 3011 Chapter 9 Diet Pill Example: Let p = true proportion of diet pill customers that lose at least 10 pounds.

...Statistical Report Writing No.3. Introduction. A federal regulatory agency is investigating an advertised claim that a certain device can increase the gasoline mileage of car. Ten of these devices are purchased and installed in cars. Gasoline mileage (mpg) for each of the cars is recorded both before and after installation. The data are listed in the following table. The columns “Before” and “After” show the mileage (mpg) before and after the installation of device, the column “Change” represents the improvement of mileage. Here we present the summary of statistics for each variables. In this study we want to determine whether there is a significant gain in mileage after the devices were installed. Data analysis and statistical test. The following figures show the histogram and the normal quantile plot (QQ plot) for the variable “Change”. Note that the sample size is small. Thus, the reliability of statistical test is dependent on the ability to assume that the data come from a normal distribution. In particular, we need to assess the normality for the variable “Change” since it is used for a statistical test. The histogram (above left) displays neither a center nor symmetry of distribution. Rather, it is bimodal, suggesting that there are two distinct populations to which the effect of device could be different. The QQ plot (above right) also indicates that the plots do not follow the straight line. Thus, the normality of data cannot be assumed, making...

Some new machinery is being evaluated with the aim of increasing the daily mean yield without changing the population standard deviation σ. Hypothesis Testing: Evaluating the effectiveness of new machinery at the Bloggs Chemical Plant Null hypotheses • The claim tested by a statistical test is called the null hypothesis. The test is designed to assess the strength of the evidence against the null hypothesis. Usually the null hypothesis is a statement of “no effect” or “no difference”, that is, a statement of the status quo. Alternative hypotheses • The claim about the population that we are trying to find evidence for is the alternative hypothesis. The alternative hypothesis is one-sided if it states that a parameter is larger than or...

In a statistics course, a linear regression equation was computed to predict the final exam score from the first quiz score. The equation obtained was Y = 10 + 0.9 X, where Y is the final exam score and X is the first quiz score. A prediction interval for Al Bundy who scored 95 on the first quiz and on the final exam scored 98 was computed. Also a confidence interval for mean score of 95 on the first quiz was computed. From this we can conclude: a) Al Bundy’s prediction interval in wider than the confidence interval. b) Al Bundy’s prediction interval in shorter than the confidence interval. c) Al Bundy’s prediction interval is equal in length to the confidence interval. d) None of the above 4.

...several in-class assignments will be given throughout the semester. Examination • There will be two mid-term examinations in this course and a final exam. The final exam is cumulative but it will be more focused on the material up to the preceding exam. • Both exams will be closed book, notes, laptops, PDAs, etc., except you will be provided with a “cheat sheet”. Calculators are allowed. • Exams are meant to be objective tests of the knowledge and skills you gained during the course. Reading the assigned chapters, working on the assigned problems, and participating in class sessions are the best ways of preparing for the exam. The exams are likely to include problems similar to those assigned or covered in class and some multiple choice and/or true-false questions. • No makeup exams will be given. If you miss an exam without a documented excuse (see NEU student handbook) you will receive a zero for the exam. Generally, absence from an exam will be excused only for illness upon presentation of a letter from your doctor. Project There will be a team-based Project. Details of this project will be provided early in this semester.

...13,16,20 Ch 7 14 Ch 8 18 Ch 9 17 Ch 11 11 & 12 13 - List the five steps of hypothesis testing and explain the procedure and logic of each. Answer: First step: The first step in hypothesis testing is to specify the null hypothesis (H0) and the alternative hypothesis (H1). Second step: In this step we have to select significance level. If significance level is not given then 0.05 or the 0.01 level is used. Third step: Calculate the test statistic. The third step is to calculate a statistic analogous to the parameter specified by the null hypothesis. Fourth step: The fourth step is to calculate the p-value which is the probability of the test statistic and find the rejection region. Fifth step: The fifth and final step is to draw and describe conclusions. The probability value computed in 4th step is compared with the significance level selected in step 2. If the probability is less than or equal to the significance level, then the null hypothesis is rejected. If the probability is greater than the significance level then the null hypothesis is not rejected. 16 - Based on the information given for each of the following studies, decide whether to reject the null hypothesis. For each, give the Z-score cutoff (or cutoffs) on the comparison distribution at which the null hypothesis should be rejected, the Z score on the comparison distribution for the sample score, and your conclusion.
