Find test statistic
Transcribed Image Text:An experiment was conducted to determine whether giving
candy to dining parties resulted in greater tips. The mean
tip percentages and standard deviations are given in the
accompanying table along with the sample sizes. Assume
that the two samples are independent simple random
samples selected from normally distributed populations,
and do not assume that the population standard deviations
are equal. Complete parts (a) and (b).
OA. Ho: H₁ H¹4₂
H₁: M₁ <H₂
a. Use a 0.01 significance level to test the claim that giving candy does result in greater tips.
What are the null and alternative hypotheses?
O C. Ho: H1 = 2
H₁:₁> H₂
No candy
Two candies
B. Ho: ₁ = ₂
H₁: H₁ H₂
D. Ho: H₁ = H₂
H₁: M₁ <H₂
The test statistic, t, is - (Round to two decimal places as needed.)
