A production line operation is designed to fill cartons with laundry detergent to a mean weight of 32 ounces. A sample of carton
IgorLugansk [536]

Answer:

Step-by-step explanation:

a) The null hypothesis states that

The production line operation fills cartons with laundry detergent to a mean weight of 32 ounces.

H0 : µ = 32

The alternative hypothesis states that

The production line operation overfills or under fills cartons with the laundry detergent to a mean weight of above or below 32 ounces.

Ha : µ ≠ 32

b) when the calculations are done and the p value is determined, then it would be compared with the level of significance

When the significance level is lesser than the p value, we do not reject H0 because there is no sufficient evidence to conclude that the production line operation overfills or under fills cartons.

c) When the significance level is greater than the p value, we would reject H0 because there is sufficient evidence to conclude that the production line operation overfills or under fills cartons.

The cost of material used in making a Frisbee varies directly with the square of its diameter. If it costs the manufacturer $0.4
Rama09 [41]

Answer:

c = $0.8

Step-by-step explanation:

Let

cost of material = c

Diameter = d

c = k*d²

If it costs the manufacturer $0.45 for the material of a Frisbee with a 9-inch diameter

c = k*d²

0.45 = k * 9²

0.45 = k * 81

0.45 = 81k

k = 0.45/81

k = 0.0055555555555

what is the cost for the material for a Frisbee with a 12-inch diameter

c = k*d²

c = 0.0055555555555 * 12²

c = 0.0055555555555 * 144

c = $0.8
