This Question: 1 pt 300f 30 (28 complete) This Test: 30 pts A data set about speed dating includes "ike" ratings of male dates made by the female dates. The significance level to test the claim that the population mean of such ratings is less than 6.00. Assume that a simple random sa and altenative hypotheses, test statistic, P.value, and state the final conclusion that addresses the original claim. What are the null and altemative hypotheses? summary statistics are n 194, x-5.57, s 1.96. Use a 0.05 OA. Ho: -6.00 O B. H1 : #800 c. Ho: = 6.00 Ho : 6.00 H1: 6.00 Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value (Round to three decim al places as needed.) State the final conclusion that addresses the original claim. Click to select your answer(s). Step 1 of S A esc

Explanation / Answer

The statistical software output for this problem is:

One sample T summary hypothesis test:
: Mean of population
H0 : = 6
HA : < 6

Hypothesis test results:

Hence,

Null and Alternative Hypotheses: Option C is correct.

Test statistic = -3.06

P - value = 0.001

Reject Ho; Sufficient evidence to support the claim that mean is less than 6.

Mean Sample Mean Std. Err. DF T-Stat P-value 5.57 0.1407198 193 -3.0557178 0.0013
