A researcher takes sample temperatures in Fahrenheit of 19 days from Pittsburgh (Group 1) and 16 days from San Antonio (Group 2). Test the claim that the mean temperature in Pittsburgh greater than the mean temperature in San Antonio. Use a significance level of a = 0.01. Assume the populations are approximately normally distributed with unequal variances. You obtain the following two samples of data. Round answers to 4 decimal places. Pittsburgh San Antonio 64.6 60.9 53.1 47.8 41.3 54.1 64.1 56.7 59.6 61.9 41.3 53.1 63.4 69.2 73.9 55.6 60.4 80.2 69.8 65 80.9 38.2 p-value= 52 71.3 63.2 39.2 89.7 89.7 20.1 72.3 39.2 71.3 57.6 68.3 53.6 What are the correct hypotheses? Note this may view better in full screen mode. Select the correct symbols for each of the 6 spaces. Ho: U H₁:₁ Based on the hypotheses, find the following: Test Statistic = X The p-value is greater than alpha OH₂ H₂ oto alpha. The correct decision is to fail to reject the null hypothesis 0 The correct summary would be: There is not enough evidence to support temperature in Pittsburgh greater than the mean temperature in San Antonio. o the claim that the mean
