Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

required hypothesis test about the mean, µ, of the population from which the sample was drawn. Use the critical-
value approach.
Sample mean = 7.5
S = 1.8
n = 18
a = 0.01
Ho: H = 10
H1: H <10
1. The test statistics is
(Round to three decimal places)
2. The critical value(s) is/are
(If there are two critical values separate each with a comma.)
3. The decision is to
the null hypothesis. (Enter R if you reject and enter Fif you fail to reject)
