The university claims that the average result of students in an exam was 98.6. The students don't believe this and would like to validate this claim. They collected a sample of 50 students and found that the sample mean is 98.26 and the sample standard deviation to be 0.765. The standard error of the randomization distribution is 0.1066. If we assume that the alternative hypothesis that the population mean doesn't equal 98.6 and using a significance level of 0.05, then p-value
a. we accept the null hypothesis as the p-value is 0.0007
b. we accept the null hypothesis as the p-value is 0.1
c. we reject the null hypothesis as the p-value is 0.1
d. we reject the null hypothesis as the p-value is 0.0014
e. we accept the null hypothesis as the p-value is 0.005
f. we reject the null hypothesis as the p-value is 0.005
g. we accept the null hypothesis as the p-value is 0.0014
h. we reject the null hypothesis as the p-value is 0.0007
