men and 160 women rate the customer service as excellent. What percentage of men gave an excellent rating? What percentage of women gave an excellent rating? What was the total percentage of customers giving an excellent rating?
a)70%, 64%, 67%
b)70%, 64%, 70%
c)70%, 66%, 67%

Answer:

a) 70%, 64%, 67%

Step-by-step explanation:

Total customers surveyed = 500

Number of men = 250

Number of women = 250

Number of men who rated the customer service excellent = 175

Number of women who rated the customer service excellent = 160

Total number of customers who rated the customer service excellent = $175+160 =335$

Percentage of men who rated the customer service excellent

⇒ $\frac{\textrm{Number of men who rated excelent}}{\textrm{Total number of men}}\times 100$

⇒ $\frac{175}{250}\times 100$

⇒ 70%

Percentage of women who rated the customer service excellent

⇒ $\frac{\textrm{Number of women who rated excelent}}{\textrm{Total number of men}}\times 100$

⇒ $\frac{160}{250}\times 100$

⇒ 64%

Percentage of customers who rated the customer service excellent

⇒ $\frac{\textrm{Number of customers who rated excelent}}{\textrm{Total number of men}}\times 100$

⇒ $\frac{335}{500}\times 100$

⇒ 67%

So, the correct order is : 70%, 64%, 67% (Answer)

SVETLANKA909090 [29]

To arrive at the answer, I graphed the piecewise function using a graphing calculator, then evaluated it at x=38 and x=52. I drew a line at y=445 and found the point of intersection on the graph.

a) The difference between earnings for 52 hours ($580) and earnings for 38 hours ($380) is $200.

b) An employee must work 43 hours to earn $445.

I am going to use the binomial approximation to the normal to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

$E(X) = np$

The standard deviation of the binomial distribution is:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

When we are approximating a binomial distribution to a normal one, we have that $\mu = E(X)$ , $\sigma = \sqrt{V(X)}$ .

In this problem, we have that:

$n = 15000, p = 0.09$

So

$\mu = E(X) = np = 15000*0.09 = 1350$

$\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{15000*0.09*0.91} = 35.05$

What is the probability that at least 1,500 will agree to respond

This is 1 subtracted by the pvalue of Z when X = 1500-1 = 1499. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{1499 - 1350}{35.05}$

$Z = 4.25$

$Z = 4.25$ has a pvalue of 1.

1 - 1 = 0

0% probability that at least 1,500 will agree to respond

Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the differenc

Mademuasel [1]

Let X is the random number Erik thinks of, and Y is the random number Nita thinks of.
Both X and Y are in the range from 0 to 20.
<span>X<=20
Y<=20
If the difference between their two numbers is less than 10, then Erik wins.
The difference between the two numbers can be written X-Y, or Y-X depending on which number (X or Y) is greater. But we do not know that. In order not to get negative value, we calculate absolute value of X-Y, written |X-Y| which will give positive value whether X is greater than Y or not.
If |X-Y|<10 Erik wins.
