**Study on Hospital Stays for Congestive Heart Failure Patients**A study involving the economic burden of congestive heart failure found that the lengths of hospital stays for patients are not normally distributed with a mean of 7.8 days and a standard deviation of 9.1 days. A random sample of size 40 is taken. Which of the following best describes the sampling distribution of the sample mean?**Select one:**- a. Normal- b. Approximately normal- c. UnknownThis is an example of using the Central Limit Theorem (CLT) in statistics. The CLT states that when a sufficiently large sample size is taken from a population (usually n > 30), the sampling distribution of the sample mean will be approximately normal, regardless of the population's distribution. In this case, since the sample size is 40, the sampling distribution of the sample mean would likely be approximately normal.

let X be the length of stays of patient in the hospital is not normal distribution with mean μ=7.8…

According to the Carnegie unit system, the recommended number of hours students should study per unit is 2. Are statistics students' study hours more than the recommended number of hours per unit? The data show the results of a survey of 11 statistics students who were asked how many hours per unit they studied. Assume a normal distribution for the population. 2, 2.9, 4.5, 0.7, 3.3, 4.5, 4.2, 1.2, 0.9, 1.8, 2.8 What can be concluded at the αα = 0.05 level of significance?

Thus, the final conclusion is that ... The data suggest the populaton mean is significantly more than 2 at αα = 0.05, so there is enough evidence to conclude that the population mean study time per unit for statistics students is more than 2. The data suggest the population mean is not significantly more than 2 at αα = 0.05, so there is enough evidence to conclude that the population mean study time per unit for statistics students is equal to 2.
