Explanation / Answer

Two-Sample T-Test and CI: percent for company, percent for ceo

Two-sample T for percent for company vs percent for ceo

                       N    Mean    StDev    SE Mean
percent for company 8    15.13 8.25        2.9
percent for ceo        8    12.75     8.12        2.9

Difference = (percent for company) - (percent for ceo)
Estimate for difference: 2.38
90% CI for difference: (-4.87, 9.62)
T-Test of difference = 0 (vs ): T-Value = 0.58 P-Value = 0.572 DF = 13

p-value = 0.572 > 0.10

hence we fail to reject the null hypothesis

option E) is correct p-value for two-tailed test = 2 P(t > |T|)

hence

area will be more than 1.918 and less than -1.918
