Hypothesis Test of Mean


Press STAT and the right arrow twice to select TESTS. Use the down arrow to select

Use right arrow to select Stats (summary values rather than raw data). Enter hypothesized mean, standard deviation, mean, and
sample size. Press down arrow to select Calculate and press ENTER.

Results: Since the pvalue is 0.1, do not reject the null
hypothesis with an alpha value of 0.10 or smaller (10% level of significance
or smaller). 
Hypothesis Test of Mean


Press STAT and the right arrow twice to select TESTS. Use the down arrow to select

Use right arrow to select Stats (summary values rather than raw data). Enter standard deviations, mean and sample size for
samples 1 and 2. Press down arrow to select Calculate and press ENTER.

Results: Since the pvalue is 0.004, reject the null hypothesis
with an alpha value of 0.10 or smaller (10% level of significance or
smaller). Conclude that the two population means are not different. 
Hypothesis Test of Proportion


Press STAT and the right arrow twice to select TESTS. Use the down arrow to select Press ENTER.


Enter hypothesized proportion, number of favorable outcomes,
X, sample size, n, and select the alternate hypothesis. Use down arrow to select Calculate and press ENTER. 

Results: Since the pvalue is near zero, reject the null
hypothesis. Conclude that the sample
proportion of 0.15 is significantly different from the hypothesized
proportion of 0.52. 

Hypothesis Test of Proportion


Press STAT and the right arrow twice to select TESTS. Use the down arrow to select Press ENTER.


Enter number of favorable outcomes and sample size of
samples 1 and 2. Select the alternate
hypothesis. Use down arrow to select Calculate and press ENTER. 

Results: Since the pvalue is near zero, reject the null
hypothesis. Conclude that the sample
1 proportion of 0.90 is significantly greater than sample 2 proportion of
0.50.
