Answer:

The number of cookies baked is 50

Step-by-step explanation:

Given as:

Lacey baked 20 cookies with 2 scoops of flour

∵ For 2 scoops of flour , The number of cookies baked is 20

so,For 1 scoops of flour , The number of cookies baked is \frac{20}{2}

∴ For 5 scoops of flour , The number of cookies baked is  \frac{20}{2} × 5

I.e Number of baked cookies = 10 × 5 = 50

Hence The number of cookies baked is 50  Answer

Answer:

a) H0 : u = 28.5%

H1 : u < 28.5%

b) critical value = - 1.645

c) test statistic Z= - 1.41

d) Fail to reject H0

e) There is not enough evidence to support the professor's claim.

Step-by-step explanation:

Given:

P = 28.5% ≈ 0.285

X = 210

n = 800

p' = \frac{X}{n} = \frac{210}{800} = 0.2625

Level of significance = 0.05

a) The null and alternative hypotheses are:

H0 : u = 28.5%

H1 : u < 28.5%

b) Given a 0.05 significance level.

This is a left tailed test.

The critical value =

-Z_0.05 = -1.645

The critical value = -1.645

c) Calculating the test statistic, we have:

Z = \frac{p' - P}{\sqrt{\frac{P(1-P)}{n}}}

Z = \frac{0.2625 - 0.285}{\sqrt{\frac{28.5(1-28.5)}{800}}}

Z = -1.41

d) Decision:

We fail to reject null hypothesis H0, since Z = -1.41 is not in the rejection region, <1.645

e) There is not enough evidence to support the professor's claim that the proportion of obese male teenagers decreased.
