Suppose that data are collected from a random sample of 48 male students and 91 female students at a college in the southeast. The students are ask if they usually eat three meals a day or if they rarely eat three meals a day. The results are in the table below. Is there convincing evidence that the proportions falling into these two categories are different (not the same) for males and females? Use .05 as the level of significance.

Before the furniture store began its ad campaign, it averaged 182 customers per day. The manager is investigating if the average has changed since the ad came out. The data for the 11 randomly selected days since the ad campaign began is shown below: 194, 170, 172, 180, 151, 169, 179, 181, 167, 170, 194 Assuming that the distribution is normal, what can be concluded at the a = 0.01 level of significance? %3D a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: ? v Select an answer v H1: ? v Select an answer ♥ c.

A governmental agency computed the proportion of violent crimes in the United States in a particular year falling into each of four olo categories. A simple random sample of 550 violent crimes committed in California during that year were categorized in the same way. The following table presents the results. U.S. California Category Proportion Frequency Murder 0.012 Forcible Rape 0.058 20 Robbery 0.360 207 Aggravated Assault 0.570 318 Send data to Excel Can you conclude that the proportions of crimes in the various categories in California differ from those in the United States as a whole?

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
