Business Statistics hw help please.

I have two questions I'm having difficulty with for my stat's hw.

1.) A random sample of 20 observations produced a sample mean https://vista8.kent.edu/webct/Relati...es/f1q10-1.png = 92.4 and *s* = 25.8. What is the value of the standard error of https://vista8.kent.edu/webct/Relati...es/f1q10-2.png?

and

2.) Let the random variable X represent the amount of money carried by a student in class. To determine μ , the mean amount of money carried by a student, an experiment was conducted in class. The class was divided into four groups, and random samples from each group was taken. From Groups 1 and 2, random samples of size *n=5* were taken, while from Groups 3 and 4, random samples of size *n=10* were taken. Some sample results for the four groups are shown below. Group

Average

1

12.20

2

5.60

3

14.00

4

62.40

Your instructor is interested in testing the following hypothesis about the mean amount of money carried by a student:

H0: μ ≤ 29.05

H1: μ > 29.05

Assume that the amount of money carried by a student follows a Normal distribution, and *s**2 = 4929.1*. Using the average results for Group 2 from the above table, what is the *p-value* for this test?

any help or pointers would be very appreciated!
