Answer:
Closest standard deviation of W = 4.11
Step-by-step explanation:
Randomly selected workers = n =300
Probability of workers arriving between 6:45 to 7:00 A.M = p = 6% = 0.06
According to binomial distribution:
mean = μ = n.p
= 300(0.06) = 18
variance = σ² = n.p(1-p)
= (300)(0.06)(1-0.06)
= (18)(0.94)
= 16.92
standard deviation = σ = 4.11

Answer:
look at the explanation
Step-by-step explanation:
In order to solve this, we'll set up a proportion.
Since y is inversely related to the square of x, therefore:
y=4/63 ----->9 (square of x)
y=?
25 (square of x)
According to the inverse relation:
y=4/63------->25
y=? --------
-->9 and y=4/175
The range of the set of scores is 13.
Here,
The set of scores:
7, 8, 11, 15, 17, 20
We have to find the range of the set of scores.
What is Range of set?
The range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set.
Now,
The highest number = 20
The lowest number = 7
Hence, Range of the data set = 20 - 7 = 13
So, The range of the set of scores is 13.
