Answer:

Step-by-step explanation:

The dress costs 45% less than $69.50

45% of $69.50 is $(0.45)(69.50)=31.275$

We subtract 31.275 from 69.50 to get the sale price.

Sale Price = $69.50-31.275=38.225$

Rounding to 2 decimal places, the sale price is $38.23 (answer choice A is right)

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.
