June 2, 243 Answer using the hypothesis test.

Answer 1

The hypothesis being tested is:

H₀: µ_d = 0

H_a: µ_d ≠ 0

Jersey Mike's	Subway's
1643	1750
1878	1900
2243	1822
2001	1981
1,941.25	mean Jersey Mike's
1,863.25	mean Subway's
78.000	mean difference (Jersey Mike's - Subway's)
234.690	std. dev.
117.345	std. error
4	n
3	df
0.665	t
.5538	p-value (two-tailed)

The test statistic, t = 0.665

The p-value is 0.5538.

Since the p-value (0.5538) is greater than the significance level (0.05), we fail to reject the null hypothesis.

Therefore, we cannot conclude that there is a difference between sandwich sales.
