Question

26. Consider the following hypothesis test: $H_0: \mu = 100$ $H_a: \mu \neq 100$ A sample of 65 is used. Identify the $p$-value and state your conclusion for each of the following sample results. Use $\alpha = .05$. a. $\bar{x} = 103$ and $s = 11.5$ HIDE ANSWER Answer: Between .02 and .05 using Excel: $p$-value = $2*[1 - T.DIST(2.10,64, TRUE)] = .0397$ reject $H_0$

          26. Consider the following hypothesis test:
$H_0: \mu = 100$
$H_a: \mu \neq 100$
A sample of 65 is used. Identify the $p$-value and state your conclusion for each of the
following sample results. Use $\alpha = .05$.
a. $\bar{x} = 103$ and $s = 11.5$
HIDE ANSWER
Answer:
Between .02 and .05
using Excel: $p$-value = $2*[1 - T.DIST(2.10,64, TRUE)] = .0397$
reject $H_0$

26. Consider the following hypothesis test:
H0: μ = 100
Ha: μ≠ 100
A sample of 65 is used. Identify the p-value and state your conclusion for each of the
following sample results. Use α = .05.
a. x̅ = 103 and s = 11.5
HIDE ANSWER
Answer:
Between .02 and .05
using Excel: p-value = 2*[1 - T.DIST(2.10,64, TRUE)] = .0397
reject H0
