The National Sleep Foundation asked a random sample of 1010 US adults questions about their sleep habits. One of the questions asked about snoring. Of the 995 respondents, 37% of adults reported that they snored at least a few nights a week during the past year. When split into two age categories, 26% of the 184 people under 30 snored, compared with 39% of the 811 in the older group. Could this be considered a significant difference? Let the older group be considered group 1. What would be the correct null and alternative hypothesis for this scenario?

1. Ho:

Ha:

2. What would be the correct value of the pooled proportion? Use the sample proportions above to find your answer to four decimal places.

3. What would be the correct value of the test statistic? Give your answer to two decimal places.

4. What would be the correct p-value? Round your answer to four decimal places.

Based on the sample, we will  ["reject", "fail to reject", "accept"] the null hypothesis. There ["is", "is not"]  enough evidence to suggest that there is a difference in the rate of snoring between older adults and younger folk.

The National Sleep Foundation surveyed representative samples of adults in six different countries to ask questions about sleeping habits.† Each person in a representative sample of 250 adults in each of these countries was asked how much sleep they get on a typical work night. For the United States, the sample mean was 391 minutes, and for Mexico the sample mean was 426 minutes. Suppose that the sample standard deviations were 27 minutes for the U.S. sample and 42 minutes...

REM (rapid eye movement) sleep is sleep during which most dreams occur. Each night a person has both REM and non-REM sleep. However, it is thought that children have more REM sleep than adults†. Assume that REM sleep time is normally distributed for both children and adults. A random sample of n1 = 11 children (9 years old) showed that they had an average REM sleep time of x1 = 2.5 hours per night. From previous studies, it is known...

REM sleep is when most people dream. Each night, adults have both REM and non-REM sleep. It is thought that children have more REM sleep than adults. A random sample of 10 children had an average REM sleep time of 2.8 hours. A random sample of 10 adults had an average REM sleep time of 2.1 hours. From previous studies, the standard deviations are known to be 0.5 hour for the children’s group and 0.7 hour for the adult group....

In a survey of families in which both parents work, one of the questions asked was, "Have you refused a job, promotion, or transfer because it would mean less time with your family?" A total of 200 men and 200 women were asked this question. "Yes" was the response given by 26% of the men and 22% of the women. Based on this survey, can we conclude that there is a difference in the proportion of men and women responding...
