A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=15, ¤=137.33, s=24.12. Use a 0.01 significance level to test the claim that the population mean of such ratings is greater than 110. Assume that a simple random sample has been selected. Identify the n and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. The Hypotheses Test Но: р 3 110 H1: Choose one of these A:u > 110 B: µ < 110 C: µ# 110 Test statistic Choose one of these (A) t = 4.39; (B) z = 4.39 P value < s.f. = 0.10 ( reject or do not reject) (Round to three decimal places as needed. )

Question
Transcribed Image Text:A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=15, ã=137.33, s=24.12. Use a 0.01
significance level to test the claim that the population mean of such ratings is greater than 110. Assume that a simple random sample has been selected. Identify the null
and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
The Hypotheses Test
Ho: µ = 110
H1:
Choose one of these A:u > 110
Β:μ< 110
C: µ + 110
Test statistic
Choose one of these
(A) t = 4.39; (B) z = 4.39
P value
< s.f. = 0.10
( reject or do not reject)
(Round to three decimal places as needed. )
