Compute the test value. Wind Speed (Independent Samples Z - p - value) The average wind speed in Casper has been found to be 12.85 miles per hour, and in Phoenix, it is 7.9 miles per hour. To test the relationship between the averages, the average wind speed was calculated for a sample of 31 days for each city. The results are reported below. Is there sufficient evidence at ? = 0.05 to conclude that the average wind speed is greater in Casper than in Phoenix? The table has three columns. The line in first column is blank and the second row is sample size, third row is sample mean, and last row is population standard deviation. The next column is titled casper on the first row and on second row is 31, then 12.85, and 3.3 on the last row. The last column is titled Phoenix with 31 on the second row, then 7.9, and 2.8 on the last row. Step 1: State the hypotheses as an if then statement
