Question

The one-sample t statistic for testing

H₀: μ = 8

H_a: μ > 8

from a sample of n=22 observations has the value t = 2.24

a) What are the degrees of freedom for this statistic? Blank 1

b) (report to 3 decimal places) Give the two critical values t* from Table D that bracket t:

Lower: Blank 2 Upper: Blank 3

c) (report to 2 decimal places) Between what two values does the P-value of the test fall?

Lower: Blank 4 Upper: Blank 5

d) Is the value t = 2.24 significant at the 5% level? (yes/no) Blank 6

What about at the 1% level? (yes/no) Blank 7
