Complete Question:
A supervisor finds the mean number of miles that the employees in a department live from work. He finds x=2.9 and s=3.6. Which statement must be true?
z376 is within 1 standard deviation of the mean.
z37 is between 1 and 2 standard deviations of the mean.
z37 is between 2 and 3 standard deviations of the mean.
z37 is more than 3 standard deviations of the mean.
Answer:
z37 is between 2 and 3 standard deviations of the mean.
Explanation:
Standard deviation is a way of measuring of how much the value sample varies or disperses. A low standard deviation means that the values are near the mean value of the set, whereas a high standard deviation implies that the values are distributed over a wider range.
In reasonably average data sets, the values reflect about 68 per cent of the sample within 1 standard deviation from the mean; about 95 per cent in 2 standard deviations; and about 99.7 per cent within 3 standardized deviations.
<span>A single sales call to a potential B2B buyer in the United States could cost about $400. A B2B sales call is a business to business sales call. The closing of a sale can be hit or miss, but it is said that any contact with the buyer can be helpful later.</span>
Original price = $500
Assume that the tax rate is 8%
Cost of the TV plus tax = 500*1.08 = $540
Worth of the 25% coupon = 0.25*540 = $135
Reduced price = 540 - 135 = $405
The cost of the TV with a coupon for 25% off excluding tax is $405.
Answer: $405
Answer:
d. All of the last 12 payments he received are taxable.
Explanation:
In the case when the life expectancy is 180 months and collected 192 payments prior he died
So according to the question, all the 12 payments would be received are taxable
Here the payment that received for 180 months would not be involved in the gross income and the remaining 12 payment would be taxable
Therefore the option d is correct
