Expert Answer

Step 1

The null and the alternative hypotheses are given below:

H­­0: The mean assembly time taken by two methods A and B are same.

HA: The mean assembly time taken by two methods A and B are different.

It is given that 0.80 as the test statistic, 0.01 as the level of significance and 0.4292 as the p-value

Step 2

Decision Rule:

Reject the null hypothesis H0 when the p-value is less than or equal to the level of si...
