The area head of GLOBE Broadband claims that more than 75 percent of his customers in Metro Manila are satisfied with the services they received. To test this claim, the local newspaper randomly surveyed 400 customers online and found out that 320 customers were satisfied and the remaining were unsatisfied. Test this claim at alpha value of 10% level of significance. The critical value of z for this test about single proportion is; z = 1.28 z = 1.645 z = 2.33 .The computed value of z test statistic for this single proportion problem is; z = 0.05 z = 2.27 z = 2.92 The computed value of z test statistic for a single proportion of this problem is greater than the critical value.? and Based from the computed value of z - test statistic for single proportion the null hypothesis of this study will be rejected.?

The area head of GLOBE Broadband claims that more than 75 percent of his customers in Metro Manila are satisfied with the services they received. To test this claim, the local newspaper randomly surveyed 400 customers online and found out that 320 customers were satisfied and the remaining were unsatisfied. Test this claim at alpha value of 10% level of significance. The critical value of z for this test about single proportion is;
z = 1.28
z = 1.645
z = 2.33
.The computed value of z test statistic for this single proportion problem is;
z = 0.05
z = 2.27
z = 2.92
The computed value of z test statistic for a single proportion of this problem is greater than the critical value.? and Based from the computed value of z - test statistic for single proportion the null hypothesis of this study will be rejected.?
