Answer 1

(a) The hypothesis being tested is:

H0: µ1 = µ2

H1: µ1 ≠ µ2

COMPANY A	COMPANY A
2.6375	2.9	mean
0.5	0.6	std. dev.
8	12	n
	-0.2625000	difference (COMPANY A - COMPANY A)
	0.2474874	standard error of difference
	0	hypothesized difference
	-1.06	z
	.2888	p-value (two-tailed)

The p-value is 0.2888.

Since the p-value (0.2888) is greater than the significance level (0.10), we cannot reject the null hypothesis.

Therefore, we can support the claim.

(b) The hypothesis being tested is:

H0: µ1 = µ2

H1: µ1 > µ2

COMPANY A	COMPANY A
2.638	2.900	mean
0.625	0.895	std. dev.
8	12	n
	17	df
	-0.2625	difference (COMPANY A - COMPANY A)
	0.3402	standard error of difference
	0	hypothesized difference
	-0.772	t
	.7745	p-value (one-tailed, upper)

The p-value is 0.7745.

Since the p-value (0.7745) is greater than the significance level (0.10), we cannot reject the null hypothesis.

Therefore, we cannot support the claim.
