2 answers:
Answer with explanation:
The Dot plot ,Representing Data Values at different Points are
4, 5, 4, 3, 3, 2,2,1,1,1
Arranging it in Ascending order
1,1,1,2,2,3,3,4,4,5
Number of values in data set is 10, which is even.
Median
Mean
Mode =1
Mean > Median > Mode
It means graph of the distribution will be Skewed Right.

Answer:
The correct option is;
A. 0.17
Step-by-step explanation:
The given information are;
The mean duration it takes a cashier to process an order, μ = 276 seconds
The standard deviation from the mean, σ = 38 seconds
The z-score of the order processing time of x = 240 seconds is given as follows;
Therefore;
The probability
P(z = -0.9474) = 0.17361
Therefore, the proportion of orders which are processed in less than 240 is approximately 0.17361 or 0.17 to two places of decimal.
