A researcher surveyed 300 randomly selected high school students in Utah and asked them how much sleep they had gotten the previous night. The survey resulted in a mean of 6.8 hours and a standard deviation of 1.3 hours. Compute and interpret a 95% confidence interval for the true mean amount of sleep that Utah high school students get.

In a class survey, students are asked how many hours they sleep per night. In the sample of 20 students, the mean was 5.77 hours with a standard deviation of 1.72 hours. Let's construct a 90% confidence interval for the mean number of hours slept per night in the population from which this sample was drawn.

It is believed that Lake Tahoe Community College (LTCC) Intermediate Algebra students geven hours of sleep per night, on average. A survey of 22 LTCC Intermediate Algerated a mean of 7.24 hours with a standard deviation of 1.93 hours. At a level of significance of 5%, do LTCC Intermediate Algebra students get less than seven hours of sleep per night, on average? The distribution to be used for this test is $X \sim$ _________ $$ \begin{array}{l}{\text { a. } \quad N\left(7.24, \frac{1.93}{\sqrt{22}}\right)} \\ {\text { b. } N(7.24,1.93)} \\ {\text { C. } t 22} \\ {\text { d. } t_{21}}\end{array} $$
