Answer:
The data is skewed to the bottom and contains an outlier.
Step-by-step explanation:
1. Test for outlier
An outlier is a point that is more than 1.5IQR below Q1 or above Q3.
IQR = Q3 - Q1 = 74 - 51 = 23
1.5 IQR = 1.5 × 23 = 34.5
51 - 15 = 36 > 1.5IQR
The point at 15 is an outlier.
2. Test for normal distribution
The median is not in the middle of the box.
Rather, it cuts the box into two unequal parts, so the data does not have a normal distribution.
3. Test for skewness
The longer part is to the left of the median, so the data is skewed left.
The answer is C. x=2 if that is wrong then its A but it should be C
Answer:
A. Surveying every 25,000th number
Step-by-step explanation:
If the numbers of people are assigned in order of 1 to 1 000 000 then the smallest sample would be obtained by conducting surveys every 25 000th numbers.
The calculation of the sample size would be made by dividing 1 000 000 by 25 000.
Therefore, the smallest sample selected would be 40 people.
If the surveys were made every 25th numbers, then the sample size would be:
people
You would have to do length times width. So you would do 6*6 then you will get 36. After that you would want to do 36*3. You would then get 108. The answer is B. 108 ft^2.
