Question

the test statistic of Z equals -2.63 is obtained when testing the claim that P=3/5

a. using a significance level of ?=0.10 find the critical value

b. should have weed reject ho or should we fail to reject ho

a. the critical value is/are z=
round to two decimal places as needed use a comma to separate answers as needed

B. choose the correct conclusion below

a fail to reject ho there is not sufficient evidence to Warrant rejection of that claim that P equals 3/5

b. reject ho there is not sufficient evidence to Warrant rejection of the claim that P equals 3/5

c fail to reject ho there is sufficient evidence to Warrant rejection of the claim that P equal 3/5

reject ho there is sufficient evidence to Warrant rejection of the claim that P equal 3/5

(a) Here Significance level alpha = 0.10,

Here the critical value for two tailed test as we are testing the claim that P = 3/5

So Z (critical) = +- 1.645

(b) Heere we will reject the null hypothesis as there is sufficient evidence to warrant rejection of claim that P equal to 3/5. Option D is correct.
