product placementSales have increased after the change in product placement. The appropriate hypothesis is that sales have not changed. No change in sales. Since p-value is less 0.05 there is enough evidence statistical evidence that sales have increased. Both samples come from normallydistributed populations, they are both simple random samples and each sample is less then 10% of the population.
(a) I will use two sample t test assuming Equal Variances
(b)
Ho: u1 = u2
H1: u1 < u2
since p-value is less than 0.05 so we can reject the null hypothesis and conclude that the sales have increased.
