Answer:

d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.

Step-by-step explanation:

The type 1 error could be said to have been made if the null hypothesis is erroneously rejected.

In the scenario above :

The null hypothesis (H0) : mean = 40

Hence, if the Null hypothesis defined above is rejected when in fact the hypothesis that the mean miles per gallon is actually 40.

On the other hand, the type 2 error occurs when a null which is false is not rejected.

Hence, when a true null is rejected, a type 1 error is committed. Similarly, when a false null isn't rejected, then a type 2 error has been committed.

A grocery store manager notices that this month her store sold a total of 623 gallons of ice cream, which represents a decrease
kotykmax [81]

Answer:

- The store sold 733 gallons of ice cream last month.

- The store sold 748 pounds of broccoli last month.

Step-by-step explanation:

Given

Ice\ Cream = 623

\%\ Ice\ Cream = 15\%

Broccoli = 912

\%\ Broccoli = 22\%

Solving (a): Gallons of Ice Cream

<em>Let Gallons sold last month be G1; Gallons sold this month be G2;</em>

The relationship between both is:

G2 =G1 - 15\% * G1

Substitute 623 for G2

623 =G1 - 15\% * G1

623 =G1 - 0.15 * G1

623 =G1 - 0.15 G1

623 =0.85 G1

Divide through by 0.85

G1 = 623/0.85

G1 = 732.941176471

G1 = 733

Solving (b): Pounds of Broccoli

<em>Let Pounds sold last month be P1; Pounds sold this month be P2;</em>

The relationship between both is:

P2 =P1 + 22\% * P1

Substitute 912 for P2

912 =P1 + 22\% * P1

912 =P1 + 0.22 * P1

912 =P1 + 0.22 P1

912 =1.22 P1

Divide through by 1.22

P1 = 912/1.22

P1 = 747.540983607

P1 = 748
