Based on the percentage of readers who own a particular make of the car and the random sample, we can infer that there is sufficient evidence at a 0.02 level to support the executive claim.
<h3>What is the evidence to support the executive's claim?</h3>
The hypothesis is:
Null hypothesis : P = 0.55
Alternate hypothesis : P ≠ 0.55
We then need to find the test statistic:
= (Probability found by marketing executive - Probability from publisher) / √( (Probability from publisher x (1 - Probability from publisher))/ number of people sampled
= (0.46 - 0.55) / √(( 0.55 x ( 1 - 0.55)) / 200
= -2.56
Using this z value as the test statistic, perform a two-tailed test to show:
= P( Z < -2.56) + P(Z > 2.56)
= 0.0052 + 0.0052
= 0.0104
The p-value is 0.0104 which is less than the significance level of 0.02. This means that we reject the null hypothesis.
The Marketing executive was correct.

Answer:
23.68%
Explanation:
The computation of the cost of not taking a cash discount is shown below:-
Cost of not taking a cash discount = [Discount percentage ÷ (100% - Disc.%)] × (360 ÷ (Final due date - Discount period))
= (2% ÷ 98%) × (360 ÷ (50 - 19))
= 2.04% × 11.61
= 23.68%
Therefore for computing the cost of not taking a cash discount we simply applied the above formula.
Answer:
$6910.70
Explanation:
At the end of each year, the account balance will be 1.05 times the value at the beginning of the year. Thus, at the end of year 3, the value is 1.05^3 times the original value.
$8000 = (deposit)×1.05^3
deposit = $8000/1.05^3 ≈ $6910.70
James should deposit $6910.70 today.

Answer:
Will increase
Explanation:
Substitutes are the goods which have high elastic demand or positive cross elasticity of demand. An increase in price substantially affects the demand for a substitute good. For example, if tea and coffee are substitutes, an increase in the price of coffee will increase the demand for tea and the overall surplus in the team market.
