Question

You decide to test the claim that the mean Age of TCC students is less than 30 at the .05 significance level. From your sample of 89 students, the mean age was 27.4, with a standard deviation of 9.2 years.

The alternative hypothesis is:

Ha:p≠30
Ha:μ≠30
Ha:p<30

Ha:x¯<30
Ha:μ<30

The Test Statistic is: _____________
Round to 2 decimal places.

The p- value is:_______________
Round to 4 decimal places.

Our conclusion is:

Fail to reject the null hypothesis
Reject the null hypothesis

Fail to reject our hypothesis
Reject our hypothesis

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
