9966 [12]

Answer:

As p-value = 0.0.68 > 0.05   the null hypothesis could not be rejected

Step-by-step explanation:

The computation of the p-value is shown below:

Given that

Average life = \bar x = 88.5

Standard deviation = \sigma = 9

Sample = n = 80

Based on the above information

Null and alternative hypothesis is

H_o : u = 87\\\\H_a : u > 87

Now for the level of significance \alpha = 0.05 and the critical value for a right talied test is z_c = 1.64

Now the test statistic is

z = \frac{\bar x  - u_o}{\sigma/\sqrt{n} }\\\\= \frac{88.5-87}{9/\sqrt{80} }

= 1.491

Now it is observed that

Z = 1.49≤z_ c = 1.64

So by this the null hypothesis could not be rejected

So,

P -value = 1 - P(z<1.491)

P-value = 0.068

As p-value = 0.0.68 > 0.05   the null hypothesis could not be rejected
