The computed mean and standard deviation are 79.3 and 5.95, respectively. The grade level coordinator wants to test if the true mean is greater than 75. A test of hypothesis using 0.05 level of significance will be performed. The computed value of the appropriate test statistic used is == O 2.29 -3.7 O -2.29 O 3.7

A random sample of 10 senior high school students showed the following scores in the unit test: 72 73 75 75 78 79 80 85 87 89 The computed mean and standard deviation are 79.3 and 5.95, respectively. The grade level coordinator wants to test if the true mean is greater than 75. A test of hypothesis using 0.05 level of significance will be performed. The computed value of the appropriate test statistic used is O 2.29 -3.7 O-2.29 3.7
