Question

Use technology to find the P-value for the hypothesis test described below.

The claim is that for a smartphone carrier’s data speeds at airports, the mean is u= 14 mbps. The sample size is n=18 and the test statistic is t= -2.055.

Answer 1

SOLUTION:

From given data,

Use technology to find the P-value for the hypothesis test described below.

The claim is that for a smartphone carrier’s data speeds at airports, the mean is = 14 mbps. The sample size is n=18 and the test statistic is t= -2.055.

Given that,

mean = = 14

sample size = n=18

test statistic = t = -2.055

Test Hypothesis is,

Null hypothesis

H₀ :   = 14

Alternative Hypothesis

H_a :   ​​​​​​​ 14

Degree of freedom

df = n-1 = 18-1 = 17 (two tailed)

P-value:

P-value at t = -2.055 and df = 17

P-value = 0.055579
