Answer:
The whisker box-plot that represents this data is:
Option: C
Step-by-step explanation:
We have the set of data points as:
11, 12, 15, 16, 17, 19, 22, 24, 29, 33, 38
From these data points we could observe that the:
Minimum value of whisker-box plot is: 11
Maximum value of whisker-box plot is: 38
The median is the central tendency of the data and the middle line in the box-plot represents the median.
Hence, here we have:
Median i.e. =19
Also, we know that the minimum value of the box represents the lower quartile and it is the median of the lower set of the data and is:
Also lower set of data is:
11, 12, 15, 16, 17
and the middle value of data is: 15
Hence,
Lower quartile i.e. =15
Similarly,
the minimum value of the box represents the upper quartile and it is the median of the upper set of the data.
The upper set of data is:
22,24,29,33,38
and median of the uppers set of data is 29.
Hence,
Upper quartile i..e =29.
Option: C is the correct answer.
Answer:
Zscore = 0.5
Step-by-step explanation:
If we assume a normal distribution, we mean that the diameters of each tomato follow a normal distribution. This is N~ (0,1).
By that, we mean that the mean (μ) = 0 and variance () = 1. Thus, since we are told that one tomato was in the 50th percentile. This implies the median. And is 0.5. And if the distribution is normal, the mean and median and mode should be equal.
Thus:
==> Z score = =
Answer: 1.8%
Step-by-step explanation:
Given:
Amount in the bank account = $1850
Monthly payment of can loan = $400.73
To find:
When would automatic payments make the value of the account zero?
Solution:
Craig stops making deposits to that account. So, amount $1850 in the bank account is used to make monthly payment of can loan.
On dividing the amount by monthly payment, we get
It means, the amount is sufficient for 4 payment but for the 5th payment the amount is not sufficient.
Therefore, the 5th automatic payments make the value of the account zero.
