The following table shows the average hourly wage rates for day-care centers fron two locations based on two random samples. Use the table to complete parts a through c. Location 1 Location 2 Sample mean Sample standard deviation Sample size $9.63 $1.19 26 $8.68 $1.27 32 a. Perform a hypothesis test, using a = 0.01, to determine if the average hourly wage for day-care workers in Location 1 is $0.50 per hour higher than the average hourly wage for day-care workers in Location 2. Assume the population variances for wage rates each location are equal. Determine the null and alternative hypotheses for the test. Ho: H1 -2 s S0.50 H: H-2 > $0.50 Calculate the appropriate test statistic and interpret the result. The test statistic is. (Round to two decirmal places as needed.)

Question
The following table shows the average hourly wage rates for day-care centers from two locations based on two random samples. Use the table to complete parts a through c. Location 1 Location 2 Sample mean Sample standard deviation Sample size $9.63 $1.19 26 $8.68 $1.27 32 a. Perform a hypothesis test, using a= 0.01, to determine if the average hourly wage for day-care workers in Location 1 is $0.50 per hour higher than the average hourly wage for day-care workers for wage rates Location 2. Assume the population variances each location are equal. Determine the null and alternative hypotheses for the test. Họ: H1 -H2 s S0.50 H: H1- H2 > $0.50 Calculate the appropriate test statistic and interpret the result. The test statistic is. (Round to two decimal places as needed.)
