Answer:

z=-1.591

Step-by-step explanation:

Null Hypotheses,

$H_0 : p=0.8\\H_a: p>0.80$

So we use z-test for one population proportion (right-tailed test)

According to this informaton, we defined that

$\alpha=0.05$

$z_c=1.64$ (critical value)

So our Rejection region is $R={z:z>1.64}$

$z=\frac{\bar{p}-p_0}{\sqrt{p_0(1-p_0)/n}} = \frac{0.755-0.8}{\sqrt{0.8(1-0.8)/200}}=-1.591$

Not rejection.

3/4 is 3 times 1/4, so the number of walls Dan can paint is 3 times the number of cans Dan uses.

A. 1/2 can will paint 3/2 walls, not 2.

B. 1 can will paint 3 walls — true

C. 5/3 cans will paint 5 walls — true

D. 2 cans will paint 6 walls, not 8.

E. 5/2 cans will paint 15/2 = 7 1/2 walls, not 10.

F. 11/3 cans will paint 11 walls — true
