chapter section 2 ht exercise 116 use the distnbution and the cample results complete the test t

Hello student, two samples are given sample mean of first sample is 18 .8, standard deviation is

All right, let's say we're given instructions to run a t -test at a significance level of alpha

In this question, H0 i .e. null hypothesis, nu is equal to 15 and alternate hypothesis nu is gre

In letter A, we should use the T -sudent distribution to compute the hypothesis test, which is g

So we're performing a two sample T test. And we are assuming that the two means are equal and al

Question

Chapter Section 2-HT, Exercise 116: Use the t-distribution and the sample results to complete the test of the hypotheses for the underlying distribution, assuming it is relatively normal at a 5% significance level. Assume the results come from a random sample and the sample size is small. Test Ho: μ = 120 vs Ha: μ ≠ 120 using the sample results x̄ = 112 and s = 18.4. (a) Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places. Round your answer for the p-value to three decimal places. Test statistic: t = -6.09 p-value: 0.000 Should we reject Ho? Yes, we should reject Ho.

Test Ho: μ = 120 vs Ha: μ ≠ 120 using the sample results x̄ = 112 and s = 18.4.

(a) Give the test statistic and the p-value.
Round your answer for the test statistic to two decimal places.
Round your answer for the p-value to three decimal places.

Test statistic: t = -6.09
p-value: 0.000

Should we reject Ho?
Yes, we should reject Ho.
