Question

You wish to test the following claim (H) at a significance level of a = 0.02. Hou = 79.8 Huu < 79.8 You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data: data 65.5 46 52.9 What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... less than (or equal to) a greater than a This test statistic leads to a decision to... Oreject the null accept the null

Answer 1

Test statistic,
t = (xbar - mu)/(s/sqrt(n))
t = (54.8 - 79.8)/(9.8879/sqrt(3))
t = -4.379

P-value Approach
P-value = 0.0242

p-value is greater than alpha

accept null

Option D
