Question

A doctor wants to compare the average price between two different brands of sanitizer during the COVID-19 outbreaks. For this reason, he has recorded the selling price of Brand A and B based on six and five random selected stores, respectively. The recorded prices are recorded in Table 2. Based on the sample data, at 0.01 level of significance, can we claim that the average price of Brand A is higher than Brand B? Make your conclusion using the p- value approach, with the aid of Mic. Office EXCEL

Answer 1

$H_0: μA=μB \\ H_1: μA>μB$

The p-value for one tailed test is 0.3469> 0.01

Thus H₀ is rejected.

Thus there is sufficient evidence to conclude that the average price of Brand A is higher than the average price of brand B.
