Assume that the significance level is alpha = 0.01. use the given information to find the p-value and the critical value(s). the test statistic of z = -1.74 is obtained when testing the claim that p less than 0.6.

The P-value is 0.04093 and critical value is −2.33.

Step-by-step explanation:

Given information:

Significance level, α=0.01

Test statistic of z = -1.74

Testing claim is p<0.6.

Null hypothesis :

Alternative hypothesis :

It means it is a left tailed test.

The P-value for a left-tailed test, for a significance level of α=0.01 is  0.04093.

The z-critical value for a left-tailed test, for a significance level of α=0.01 is −2.33.

Therefore the P-value is 0.04093 and critical value is −2.33.

a. she will receive a refund of $278.

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
