Answer:

Part A would be B, and Part B would be C

Step-by-step explanation:

With the graph that B shows, the distance to time ratio is cut very sharply, indicating that there wasn't a constant speed throughout the entire time, up until where the graph went from shooting upwards to slightly inclining.

With the graph that C shows, out of all of the graphs, it is the only graph that shows the fact that the person went back to their starting point, indicating that they did return home because they forgot something.

I hope this helps :)

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!
