I imagine that not everyone that visited Becky’s Store spent a lot of time and money there. If she surveys only those that did, this is not a representative sample because she is leaving out other customers. She would have no one in her sample that represents customers who spent a lot of time but no money, or little time and no money or even little time and a lot of money. These are just some examples but clearly her sample is biased.

Answer with explanation:
Test Scores of Shania's in 8 subject are: 88, 91, 85, 74, 69, 72, 80, and 87.
To calculate mean we add all the variate and divide by total number of Variate in the data set.
So, Mean of the Data set
To calculate , how much the scores on her tests vary, on average, from the mean score
We will Calculate mean absolute Deviation.
To calculate it,we will find absolute difference of each variate from mean.
| 88 - 80.75|=7.25
|91-80.75|=10.25
|85 -80.75|=4.25
|74-80.75|=6.75
......
........
Then Shania should calculate mean of the new data set obtained,which is absolute difference of each variate from mean.
→The Measure that,Shania should use to find how much the scores on her tests vary, on average, from the mean score is:
Mean absolute deviation
The geometric series is convergent and the value is 16.
<h3>How to illustrate the information?</h3>
Recall that the sum of an infinite geometric series, S, given first term, t_1, and common ratio, r, is given by:
S = t_1/(1 - r)
Note that:
3 = (4)(3/4)
9/4 = (3)(3/4)
27/16 = (9/4)(3/4)
So this a geometric series with t_1 = 4 and r = 3/4. Therefore:
4 + 3 + 9/4 + 27/16 + ... = 4/(1 - 3/4) = 4/(1/4) = 16
The correct option is 16.

Determine whether the geometric series is convergent or divergent. If it is convergent, find its sum
4+3+ 9/4 +27/16 +???
choices are
1. 3/4
2. 12
3. 4
4. divergent
5. 16
