A simple random sample of months of sales data provided the following information: Month Units Sold a. Develop a point estimate
Gnom [1K]

Answer:

a) X[bar]=93

b)S=5.39

Step-by-step explanation:

Hello!

<em>A simple random sample of 5 months of sales data provided the following information: Month: 1 2 3 4 5 Units Sold: 94 100 85 94 92 </em>

<em />

<em>a. Develop a point estimate of the population mean number of units sold per month. </em>

The variable of interest is:

X: Number of sales per month.

A random sample of n=5 months was taken, for each month, the number of units sold was recorded. To calculate the mean of the sample you have to add all the observed frequencies (Units Sold) by the sample size (n)

X[bar]= ∑X/n= 465/5=93

You can say that, on average, 93 units were sold over the 5-month period.

<em>b. Develop a point estimate of the population standard deviation.</em>

To calculate the sample standard deviation you have to calculate the variance and then its square root:

S^2= \frac{1}{n-1}[sumX^2-\frac{(sumX)^2}{n} ]

∑X= 465

∑X²= 43361

S^2= \frac{1}{4}[43361-\frac{(465)^2}{5} ]= 29

S= √29= 5.385≅ 5.39

I hope this helps!

Bad White [126]
<h2>Answer:</h2>

- 9 3 x 7 5

<h2>Step-by-step explanation:</h2>

To get the combination that would yield the greatest result if the true number are multiplied,

<em>i. multiply each given combination</em>

73 x 95 = 6935

79 x 53 = 4187

97 x 35 = 3395

93 x 75 = 6975

<em>ii. get the largest result from the results calculated above in (i)</em>

The greatest of the results is 6975, therefore the digits should be placed like so;

<u> 9 </u>  <u> 3 </u>

<u> 7 </u>  <u> 5 </u>
