You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly more than 40%. With H1 : p > 40% you obtain a test statistic of z = 1.574. Find the p-value accurate to 4 decimal places.

The p-value is 0.0577.

Step-by-step explanation:

The alternate hypothesis is:

P-value of the test:

The p-value of the test is the probability of finding a sample proportion above the one found, which is 1 subtracted by the p-value of z.

We have that z = 1.574.

Looking at the z-table, z = 1.574 has a p-value of 0.9423

1 - 0.9423 = 0.0577

The p-value is 0.0577.

answer: sensy

step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to
