Of a random sample of 381 high-quality investment equity options, 191 had less than 30% debt. of an independent sample of 166 high-risk investment equity options, 145 had less than 30% debt. test, against a two sided alternative, the null hypothesis that the two population proportions are equal.

As we have calculated Z = -8.2345 THEREFORE critical value is -1.96 hence there is significant difference ,  neglect null hypothesis.

and two population are not equal

Step-by-step explanation:

Given data:

Assuming null hypothesis be Hypothesis O (P1 = P2)

Assuming alternate hypothesis be Hypothesis A (P1 is not equal to P2)

Q = 1 - P = 0.3857

SE = 0.0452

test statics

   [taken 5% significance level]

from standard z table , critical value of

As we have calculated Z = -8.2345 THERFORE critical value is -1.96 hence there is significant difference ,  neglect null hypothesis.

and two population are not equal

a .4y4

hope this !
