Answer:
The probability that the mean test score is greater than 290
P(X⁻ > 290 ) = 0.0217
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Mean of the Population (μ) = 281
Standard deviation of the Population = 34.4
Let 'X' be a random variable in Normal distribution
Given X = 290

<u><em>Step(ii):-</em></u>
<em> The probability that the mean test score is greater than 290</em>
P(X⁻ > 290 ) = P( Z > 2.027)
= 0.5 - A ( 2.027)
= 0.5 - 0.4783
= 0.0217
The probability that the mean test score is greater than 290
P(X⁻ > 290 ) = 0.0217
Answer:
1. 5% Increase
2. 49.5 DKK for 10% discount, 74.25 DKK for 15% discount
Step-by-step explanation:
Question 1:
15 - 10 = 5
Question 2:
495 / .10 = 49.5
495 / .15 = 74.25
To get the announced price with discount use this method:
Original Price / Discount Percent (ex: 0.7 for 70% discount) = Announced Price
