Question

If a z statistic has the value z = 1.30 and says that the population mean is greater than its value under . Then the p value of the test is,

Answer 1

Answer:

The p-value will obtain a result and probability with the least extreme to be observe.

So population mean is greater than its value having a z-value at least as great in magnitude

From the z-value says 1.30. Now the p-value will be the p-value of the given are from the right is from Positive and negative from the area 1.3 to -1.3

2*P(Z > 1.30)

2*.0968

= .1936.
