so again with another p-value problem. but this time, gotta solve for t as well.
The sample mean and standard deviation from a random sample of 10 observations from a normal population were computed as x-bar = 23 and s = 9.
Calculate the value of the test statistic (3 decimals) and the p-value (4 decimals) of the test required to determine whether there is enough evidence to infer at the 5% significance level that the population mean is greater than 20.
so i get 1.054 for t which is correct:
23-20 / 9 / sqrt 10 = 1.054
now the p-value is where i have the problem...
not even sure where to start.
