Kyle purchased a 20 lb. pumpkin for $5.95. elizabeth purchased a 15 lb. pumpkin for $5.00. elijah purchased an 8 oz. pumpkin for $ 0.16. who got the best deal? who got the worst deal? what was the cost/lb. for each?

Kyle purchased a 20 lb. pumpkin for $5.95.

Cost per lb of pumpkin for Kyle = 5.95/ 12 = $0.496.

Elizabeth purchased a 15 lb. pumpkin for $5.00.

Cost per lb of pumpkin for Elizabeth = 5.00/15 = $0.333.

Elijah purchased an 8 oz. pumpkin for $ 0.16.

16 oz = 1 lb

8 oz = 0.5 lb.

Cost per lb of pumpkin for Elijah = 0.16/ 0.5 = $ 0.32.

Cost per lb of pumpkin for Elijah is $ 0.32 is the lowest price per lb of pumpkin .Cost per lb of pumpkin for Kyle is $ $0.496 is the highest price per lb of pumpkin .Therefore, Elijah got the best deal and Kyle got the worst deal.

There is not enough evidence to support the claim that drug is effective at 1%

Step-by-step explanation:

For this we use the pored test as we have dependent test;

Difference :

10,5,-5,3,-3,4,2,-3,0,10,8,-2,3,-2,5,5,4,0

Hypothesis :

H0 : μd = 0

H0 : μd ≠ 0

The mean of d, dbar = Σd / n = 44 / 18 = 2.44

The standard deviation, Sd = 4.45 (using calculator)

The test statistic, T : dbar / (Sd/√n)

T = 2.44 / (4.45/√18)

T = 2.44 / 1.0488750

T = 2.326

Degree of freedom, df = n - 1 ; 18 - 1 = 17

The Pvalue = 0.0326

α = 0.01

Since Pvalue < α ; we fail to reject H0
