Let p be a population proportion. consider the problem of testing h0 : p ≥ 0.4 based on a simple random sample of size n.(a) state the test statistic and its approximate distribution when p = 0.4 and n large enough.(b) state the rule for rejecting h0 at significance level 1% and compute its power function.(c) what is the smallest n such that the power is at least 70% when p = 0.35? (d) what is the p-value if the observed value of the sample proportion is 36% and n = 100? is h0 rejected at significance level 1%?

Step-by-step explanation:

Please see the explanation attached .

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

is there a question here?
