Suppose a recent report indicates that the mean height of girls between the ages of seven and nine is 131 cm. Rachel, a schoolnurse, collects data on a randomly selected sample of 49 girls in this age range and decides to use a hypothesis test to determinewhether the mean height is greater than reported.Which of the following hypothesis tests should Rachel use to determine if the mean height of girls between the ages ofseven and nine is greater than the reported mean of 131 cm?one-sample left-tailed z-test for a proportionone-sample right-tailed t-test for a meanone-sample two-tailed t-test for a meanone-sample right-tailed z-test for proportion

Given: Population meanμ=131Sample size(n)=49 The claim is that the height is higher than 131 cm.

Assume the managers have requested estimates of the mean attitudes towards each mall with a margin of error of 0.05 for each mall. If the managers want to have 95% confidence that the sample mean will fall within this margin of error, how large should the sample size be for each mall?

The table below summarizes data from a survey of a sample of women. Using a 0.01 significance level, and assuming that the sample sizes of 800 men and 300 women are predetermined, test the claim that the proportions of agree/disagree responses are the same for subjects interviewed by men and the subjects interviewed by women. Does it appear that the gender of the interviewer affected the responses of women?

Good credit: The Fair Isaac Corporation (FICO) credit score is used by banks and other lenders to determine whether someone is a good credit risk. Scores range from 300 to 850, with a score of 720 or more indicating that a person is a very good credit risk. An economist wants to determine whether the mean FICO score is more than the cutoff of 720. She finds that a random sample of 40 people had a mean FICO score of 760 with a standerd deviation of 95, Can the economist conclude that the mean FICO score is greater than 720? Use the a=0.01 level of significance and the P-value method with the T1-B4 Plus calculator. Part 1 of 4 State the appropriate null and altemate hypotheses.

The governor of Florida would like to estimate the mean age of all Florida residents. To do so, he randomly selects 500 Florida residents and determines their mean age to be 58.2 years. However, according the most recent census data, the mean age of all Florida residents is 55.6 years. Which of the following properly describes the 500 Florida residents who were randomly selected? sample statistic population parameter
a) TV stations use ratings to decide which shows to keep or cancel. Therefore, the A. C. Nielsen Company collects data on the TV viewing habits of Americans and publishes the information in Nielsen Report on Television. Suppose that you want to use a paired sample to decide whether the mean viewing times of married men and married women differ; Identify the variable. Identify the two populations. Identify the pairs. Identify the paired-difference variable. Determine the null and alternative hypotheses. Classify the hypothesis test as two tailed, left tailed, or right tailed. (b) State one possible advantage of using paired samples instead of independent samples
A graduate student is interested in how viewing different types of scenes affects working memory. For his study, he selects a random sample of 36 adults. The subjects complete a series of working memory tests before and after walking in an urban setting. Before the walk, the mean score on the test of working memory was 9.1. After the walk, the mean score was 1.4 higher. The graduate student has no presupposed assumptions about how viewing different types of scenes affects working memory, so he formulates the null and alternative hypotheses as: H00 : μDD = 0 H11 : μDD ≠ 0 Assume that the data satisfy all of the required assumptions for a repeated-measures t test. The graduate student calculates the following statistics for his hypothesis test: Mean difference (MDD) 1.4 Estimated population standard deviation of the differences (s) 1.6 Estimated standard error of the mean differences (sMDMD) 0.2667 Degrees of freedom (df) 35 The t statistic 5.25 The critical values of t…
A company executive claims that employees in his industry get 100 junk emails per day. To further investigate this claim, the tech department of the company conducts a study. The executive selects a random sample of 10 employees and records the number of junk emails they received that day. Here are the data: 125, 101, 109, 94, 122, 92, 119, 90, 118, 122. The tech department would like to determine if the data provide convincing evidence that the true mean number of junk emails received this day by employees of this company differs from 100. What are the appropriate hypotheses? A. H0: p = 100 versus Ha: p ≠ 100, where p = the true proportion of junk emails received this day by employees of this company B. H0: p = 100 versus Ha: p > 100, where p = the true proportion of junk emails received this day by employees of this company C.

Periodically, customers of a financial services company are asked to evaluate the company's financial consultants and services. Higher ratings on the client satisfaction survey indicate better service, with 7 the maximum service rating. Independent samples of service ratings for two financial consultants are summarized here.

Bank of America's Consumer Spending Survey collected data on annual credit card charges in seven different categories of expenditures: transportation, groceries, dining out, household expenses, home furnishings, apparel, and entertainment. Using data from a sample of 42 credit card accounts, assume that each account was used to identify the annual credit card charges for groceries (population 1) and the annual credit card charges for dining out (population 2) Using the difference data, the sample mean difference was d = $850, and the sample standard deviation was så = $1,123. a.
