(a)
χ2 = 7.4, df = 2
P-value =
State the conclusion.
Reject H0.Fail to reject H0.
(b)
χ2 = 13.1, df = 6
P-value =
State the conclusion.
Reject H0.Fail to reject H0. =
(c)
χ2 = 17.7, df = 9
P-value =

Use technology to find the P-value for the hypothesis test
described below.
The claim is that for the population of adult males, the mean
platelet count is mu μ <202. The sample size is n=55 and the
test statistic is t=−1.254.
How would I solve this using a TI-84? Please explain your steps.
Thank you!
