Question

Find the p-value for the following hypothesis test.

H0:u = 20, H1:μ≠ 20, n = 64, x = 18.75, o = 4.8

Round your answer to four decimal places.

P=?????

Answer #1

Solution :

This is the two tailed test .

The null and alternative hypothesis is ,

H0 : =20

Ha : 20

Test statistic = z

= ( - ) / / n

= (18.75- 20) / 4.8/ 64

Test statisti = -2.08

P(z < -2.08) = 0.0188 using z table

P-value = 2*0.0188=0.0376
