Arturiano [62]

Answer:

Test statistic = -2.44

There is enough evidence to support the strategist's claim.

Step-by-step explanation:

H0 : p = 0.41

H1 : p < 0.41

pˆ = 0.38

Test statistic :

z=pˆ−p/√p(1−p)/n

Z = (0.38 - 0.41) / √(0.41(1 - 0.41) / 1600

Z = - 0.03 / √0.0001511875

Z = - 0.03 / 0.0122958

Z = - 2.4399

Test statistic = -2.44

The Pvalue :

P(Z < -2.44) = 0.0073436

α - level = 0.02

If Pvalue < α ; Reject H0

0.0073436 < 0.02 ; We reject H0

Since Pvalue < α ; Hence, There is enough evidence to support the strategist's claim.

Annette [7]

Answer:

$239.68

Step-by-step explanation:

Given

Cost = $224
Sales Tax = 7%

Solving

Cost w/ Tax = Cost (1 + Tax)
Cost w/ Tax = 224 (1 + 0.07)
Cost w/ Tax = 224 * 1.07
Cost w/ Tax = $239.68
