Expert Answer

Step 1

The provided information’s are:

Sample size (n1) = 59

Sample mean of night shift = 323

Standard deviation (σ1) = 19

Sample size (n2) = 67

Sample mean of day shift = 333

Standard deviation (σ2) = 27.

Significance level (α) = 0.01

Step 2

 The null and alternative hypotheses are:
