What is the value of the test statistic?

Given the following information, the test statistic isSample Size = 49           Sample Mean = 50         Sample Standard Deviation =  7          Ho:  Mean >= 52Ha:  Mean < 52Question 9Select one:a.1b.-2c.2d.-1

Compute the P-value of the test statistic. Round the answer to four decimal places

(a) A statistician randomly sampled 100 observations and found X̄ = 106 and s = 35. Calculate the t statistic and p value for testing.     H0 : μ = 100 against HA : μ > 100.Carry out the test at the 1% level of significance.(b) Repeat part (a), with s = 25.(c) Repeat part (a), with s = 15.

Suppose that the following is to be tested: H0: p = 0.72 and Ha: p ≠ 0.72. Calculate the test statistic for thefollowing sample data: Sixty-eight out of ninety test subjects have the characteristic of interest. Round tothe nearest thousandth

The test statistic in the case described in the previous question, therefore, is:This means that:If p is really still .75, the sample proportion we got is 11.3 standard deviations below it.If p is really still .75, the sample proportion we got is 11.3 percentage points below it.If p is really still .75, the sample proportion we got is 11.3 standard deviations above it.If p is really still .75, the sample proportion we got is 11.3 percentage points above it.
