I answered part b first before a, bec6 the answer to part b is what would aid me in answering part a
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.
