3. A random sample of 200 school managers were administered a developed Leadership Skills Test. The sample mean and the standard deviation were 78 and 12 respectively. In the standardization of the test, the mean was 73 and the standard deviation was 8. Test for significance difference using a = .05 utilizing the p- value method. Ir R Step 1 Step 2 Step 3 Compute for Its value (z or t) =. Step 4 Critical Value and draw the rejection and acceptance regions Step 5 Decision and conclusion Hypotheses H: = 78 H.: Determine the level of confidence Ha: Test statistic (z or t) = CH a = DE KE

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
