1 Consider the following Give your answer bounds exactly a F

1. Consider the following. (Give your answer bounds exactly.)

(a) Find the p-value for F = 3.82, df(factor) = 2, df(error) = 20.
_________ <p<________

(b) Find the p-value for F = 4.28, df(factor) = 3, df(error) = 25.
_________ <p<________

(c) Find the p-value for F = 4.53, df(factor) = 3, df(error) = 25.

_________ <p<________

2. Use Table to find the 95% interval for r when a sample of n = 25 results in r = 0.35. (Give your answers correct to two decimal places.)

Solution

(a) Find the p-value for F = 3.82, df(factor) = 2, df(error) = 20.

p = 0.0393
___0.01__ <p<___0.05_____

-----------------------------------------------------------------

b) p = 0.0144

___0.01__ <p<___0.05____

--------------------------------------
c) p =0.0114

___0.01__ <p<___0.05____

d) r=0.35

n =25

95% confidence interval for r = (-0.052, 0.654)

= (-0.05, 0.65)
