At Istanbul University, department of Communication and Design, it is claimed that the cost for a short film assignment follows a normal distribution with mean μ=500 TL. Test the population mean at 1% significance level if the sample average is 550 TL and sample standard deviation is 114.1TL for a randomly selected 16 students.

A) What is Null hypothesis?

B) What is Null hypothesis?

C) What is Test statistic (use 3 digits after decimal point)?

D) What is Critical Value of the test at α=1% is (use 3 digits after decimal point)?

E) Does it appear at α=1% that population mean is more than 500 TL?

F) For what values of α H0 can be rejected? (%)

G) For what values of Xbar H0 can be rejected?(use 2 digits after decimal point)

URGENT. The Turkish Water Works Association reports that the per capita water use in a single-family home followed a normal distribution with mean µ=64 liters and standard deviation σ=9.4 liters per day. Mesa Mozaik is a relatively new housing development. The builders installed more efficient water fixtures, such as low-flush toilets, and subsequently conducted a survey of the residences. Twenty-nine owners responded, and the sample mean water use per day was 60 liters. At the 0.01 level of significance, is...

When σ (population standard deviation) is unknown [Critical Value Approach] The value of the test statistic t for the sample mean is computed as follows:       t =   with degrees of freedom d.f. = n – 1 where n is the sample size, µ is the mean of the null hypothesis, H0, and s is the standard deviation of the sample.       t is in the rejection zone: Reject the null hypothesis, H0       t is not in the rejection...
