lucose readings are 95, 86, 84, 107, 101, 112,85,86. The sample mean is 94.8, it is a normal distribution wirh the standard devian is 12.5, and the mean glucose is 85. Do these data indicate that Ben has an overall average level higher than 85? Use a=0.05, what is the level of significance? Compute z value of the sample test statistic. Find p value

Question
The glucose readings are 95, 86, 84, 107, 101, 112,85,86. The sample
Expert Solution
Step 1
Total data values, i.e, glucose readings (n)= 8
The following null and alternative hypotheses need to be tested:
Ho:
Ha:
This corresponds to a right-tailed test.
The z-statistic is computed as follows:
The p-value for right tailed test and z = 2.217 is , which can be found by using the standard normal table.
, the null hypothesis is rejected.
