![-
A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n = 196,
x=7.83, s=2.23. Use a 0.05 significance level to test the claim that the population mean of such ratings is less than 8.00. 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
What are the null and alternative hypotheses?
OA H₂ μ<8.00
H₁
μ> 8.00
C. H₂ = 8.00
H₁ μ<8.00
Determine the test statistic.
-1.07 (Round to two decimal places as needed)
