A researcher takes sample temperatures in Fahrenheit of 16 days from San Francisco (Group 1) and 22 days from Atlanta (Group 2). Test the claim that the mean temperature in San Francisco is less than the mean temperature in Atlanta. Use a significance level of a = 0.10. Assume the populations are approximately normally distributed with unequal variances. You obtain the following two samples of data. Round answers to 4 decimal places. San Francisco 77.4 94.8 Ho: P 77 80.9 84 73.4 84.9 92 60.6 83.6 92.5 76.3 93.4 87.2 81.5 70.4 H₁: P What are the correct hypotheses? Note this may view better in full screen mode.

The correct decision is to fail to reject the null hypothesis The correct summary would be: There is not enough evidence to support ✓✓o the claim that the mean temperature in San Francisco is less than the mean temperature in Atlanta.
