Answer:
Ashley’s backpack is the better buy.
Step-by-step explanation:
You have to calculate the price that was paid for each backpack after the discount was applied.
Ashley’s backpack: $65*0.25= $16.25
Final price= $65-$16.25= $48.75
Robbin's backpack: $75*0.3= $22.5
Final price= $75-$22.5= $52.5
According to this, the backpack that is the better buy is the one that Ashley bought because after the discounts were applied it cost $48.75 and Robbin's backpack cost $52.2 which means that Ashley's backpack was cheaper.

Answer:
B. The t test statistic is the appropriate test.
A. Reject the null hypothesis
Step-by-step explanation:
X1 = 6.841, sd1 = 0.155, n1 = 15
X2 = 6.701, sd2 = 0.108, n2 = 10
1. The appropriate test statistic for this question is the t test.
T = x1-x2/√sd1²/n1 + sd2²/n2
T = 6.841-6.701/√0.155²/15 + 0.108²/10
= 2.66
H0: u1 = u2
H1; u1>u2
Significance level = 0.05
Df = n1+n2-2
= 15+10-2
= 23
T critical = 1.714
2.66>1.714
So we have to reject the null hypothesis. Since we have enough evidence that supports this claim that fruit flavor bubble gum is on average, thicker than the fruit flavored gum.
