In testing, the null hypothesis = 25 versus the alternative hypothesis < 25, we obtained a p-value of 0.184 based on the t-statistic. Then?
Added by Denise C.
Step 1
- Null hypothesis (H0): The population mean is equal to 25 (μ = 25). - Alternative hypothesis (H1): The population mean is less than 25 (μ < 25). Show more…

A researcher comparing two groups with a t-test obtains a p-value of .19. This represents the probability of getting: the obtained test statistic is .19 if the alternative hypothesis is true a test statistic as extreme or more extreme than the obtained test statistic is .19 if the null hypothesis is true. a test statistic as extreme or more extreme than the obtained test statistic is .19 if the alternative hypothesis is true the obtained test statistic is .19 if the null hypothesis is true

A $t$ -test is conducted for the null hypothesis $H_{0}: \mu=20$ versus the alternative hypothesis $H_{\mathrm{a}}: \mu>20$ for a random sample of $n=25$ observations. The test results are $t=1.165$ and $p$ -value $=.1452 .$ a. Interpret the $p$ -value. b. What assumptions are necessary for the validity of this test? c. Calculate and interpret the $p$ -value, assuming that the alternative hypothesis was $H_{\mathrm{a}}: \mu \neq 20$ instead.
