the population mean and standard deviation are given below

Find the required probability and determine whether the given sample mean would

be considered unusual.

 

For a sample of n=75, find the probability of a sample mean

being greater than 226 if u=225 and standard deviation =3.8. (Round to four

decimal places as needed.)

 

Would the given sample mean be considered unusual? Explain your

The population mean and standard deviation are given. Find the indicated probability and determine whether the given sample mean would be considered unusual. If convenient, use technology to find the probability. For a sample of n = 36, find the probability of a sample mean being less than 12,750 or greater than 12,753 when
μ=12,750 and σ=1.7

 A leading magazine (link Barron's) reported at one time that the average number of weeks an individual is unemployed is 29 weeks. Assume that the length of unemployment is normally distributed with a population mean of 29 weeks and the population standard derivation of 4 weeks. Suppose you would like to select a random sample of 16 unemployed individuals for a follow-up study. Round the answers of the following questions to 4 decimal places.

1. What is the distribution of XX? XX-N(,)

2. What is the distribution of "xx"? "xx"-N(,)

3. What is the probability that one randomly selected individual found a job for more than 27 weeks?

You are studying the affect of financial means on students' average hours of sleep. You have found a reliable study indicating that students that have a job and do not receive financial support from their parents or guardians sleep an average of 5.8 hours per night (excluding weekends) on average (population average).
You decide to test whether or not students who do not work get more sleep per week night on average. You take a sample of 63 students that do not work and live with parents or guardians then you record the number of hours per week night they sleep for a period of 15 weeks (1 semester). You find that the average (mean) hours slept per week night in your sample is 7.2 hours and the standard deviation is 3.9 hours. Assume that average sleeping hours on week nights is normally distributed across students.
 
Remember to define the null and alternative hypotheses to help you answer the question.
