Question

Where the population standard deviation is known, the test statistic is determined to be -2.5. What is the p-value for this test?

Answer 1

Answer:

$P(Z$

Step-by-step explanation:

From the question we are told that:

Test statistic t =-2.5

Generally the equation for Test for statistics is mathematically given by

 $t=\frac{\=x-\mu}{\frac{s}{\sqrt{n} } }$

 $t=-2.5$

Therefore

P-value from Z table is

For left tailed test

 $P(Z$

therefore the P-value for the test is

 $P(Z$
