Question

Consider the following hypothesis test:

H₀: μ = 18
H_a: μ ≠ 18

A sample of 48 provided a sample mean x = 17 and a sample standard deviation s = 4.7.

a. Compute the value of the test statistic (to three decimal places.)

b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value. (to two decimal places)

p-value is between ___________ is __________

c. At α = .05, what is your conclusion?

p-value is Select greater than or equal to 0.05, reject , greater than 0.05, do not reject, less than or equal to 0.05, do not reject, less than 0.05, reject, equal to 0.05, do not reject, not equal to 0.05, do not reject, H₀

d. What is the rejection rule using the critical value?

Reject H₀ if t is Select greater than or equal to -2.012, greater than 2.012, less than or equal to -2.012 , less than -2.012, equal to 2.012, not equal to -2.012,

or t is Select greater than or equal to 2.012, greater than -2.012, less than or equal to 2.012, less than -2.012, equal to 2.012, not equal to -2.012

What is your conclusion?

t = ________ ; Select do not reject , reject H₀
