The claim is that for 12 AM body temperatures, the mean is mugreater than98.6degreesF. The sample size is n=7 and the test statistic is t=2.377.
Solution :
=
=
=
n =
This is the right tailed test .
The null and alternative hypothesis is ,
H0 :
=
98.6
Ha :
> 98.6
n =7
df = n- 1 = 7-1 = 6
t = 2.377
p value = p(t(6) > 2.377) =0.0275
P-value =0.0275

The sample size is n=3 and the test statistic is t= -1.628. This problem states to use technology but I am getting confused on to use technology I am using Statdisk
a sample of 106 body temperatures has a mean of 98.20 oF and a standard deviation of 0.62 oF. use a 0.05 significance level to test the claim that the mean body temperature of the population is equal to 98.6 oF, as is commonly believed. Find the following: A. Original claim: B. Opposite claim: C. alternative and Null Hypothesis: D. significance level: E. test statistic: F. P-vaule G. reject or fail to reject: H. final conclusion:
