The number of cell phone users has increased dramatically since 1987. According to the survey, the mean local monthly bill for cell phone users in the was P 2,497.00 in 2015. A hypothesis test is to be performed to determine whether last year's mean local monthly bill for cell phone users has decreased from the 2015 mean of P 2,497.00. Explain what each of the following would mean. а. Туре I error b. Туре II error c. Correct decision. Now suppose that the results of carrying out the hypothesis test lead to non- rejection of the null hypothesis. Classify that conclusion by error type or as a correct decision if in fact last year's mean local monthly bill for cell phone users d. equals the 2015 mean of P 2,497.00. e. is less than the 2015 mean of P 2,497.00.

1. The number of cell phone users has increased dramatically since 1987. According to the survey, the mean local monthly bill for cell phone users in the was P 2,497.00 in 2015. A hypothesis test is to be performed to determine whether last year's mean local monthly bill for cell phone users has decreased from the 2015 mean of P 2,497.00. Explain what each of the following would mean. a. Type I error b. Туре II error c. Correct decision. | Now suppose that the results of carrying out the hypothesis test lead to non- rejection of the null hypothesis. Classify that conclusion by error type or as a correct decision if in fact last year's mean local monthly bill for cell phone users d. equals the 2015 mean of P 2,497.00. e. is less than the 2015 mean of P 2,497.00.
