I NEED HELP WITH NUMBER 8 & 9

Get a random sample of n=29 from the data set.

H0: ? = 15

H1: ? ≠ 15

x f

11 6
12 7
13 5
14 4
15 2
16 1

Sampling distribution (assuming the null is true):

4. What is the mean of the sampling distribution? (+1)

mean= 15

5. What is standard error of the sampling distribution? (+1) Find it on the output. (+1)

standard error= 1.63

QUESTION:

obtained t= -8.89

8. Can you reject the null hypothesis? If so, at what significance level? (+2) Explain what this means. (+3)

9. What is the critical t? (+1)

    A random sample of size n= 15 obtained from a population that is normally distributed results in a sample mean of 45.8 and sample standard deviation 12.2. An independent sample of size n = 20 obtained from a population that is normally distributed results in a sample mean of 51.9 and sample standard deviation 14.6. Does this constitute sufficient evidence to conclude that the population means differ at the a = 0.05 level of significance? Click here to view the...

    A random sample of 16 values is drawn from a mound-shaped and symmetric distribution. The sample mean is 9 and the sample standard deviation is 2. Use a level of significance of 0.05 to conduct a two-tailed test of the claim that the population mean is 8.5. (a) Is it appropriate to use a Student's t distribution? Explain. Yes, because the x distribution is mound-shaped and symmetric and σ is unknown. No, the x distribution is skewed left.      No, the...
