A retail store wants to determine if there is a significant difference in sales between two different store locations. The store manager randomly selects 30 days from each location and records the total sales for each day. The data is shown below:

Location A: $4,500 $4,300 $4,200 $4,100 $4,400 $4,600 $4,500 $4,400 $4,300 $4,500
$4,700 $4,600 $4,400 $4,500 $4,300 $4,200 $4,100 $4,300 $4,200 $4,400
$4,300 $4,200 $4,500 $4,600 $4,700 $4,400 $4,200 $4,300 $4,500 $4,600

Location B: $3,800 $3,600 $3,500 $3,400 $3,700 $3,900 $3,800 $3,700 $3,600 $3,800
$4,000 $3,900 $3,700 $3,800 $3,600 $3,500 $3,400 $3,600 $3,500 $3,700
$3,600 $3,500 $3,800 $3,900 $4,000 $3,700 $3,500 $3,600 $3,800 $3,900

Assuming equal variances and a significance level of 0.05, is there a significant difference in sales between the two locations? Show all calculations and write a conclusion.
