Answer:
The lengths from 32.1cm to 46.5cm covers 99.7% of this distribution.
Step-by-step explanation:
The 68-95-99.7 rule states that, for normally distributed measures:
68% of the values are within 1 standard deviation of the mean.
95% of the values are within 2 standard deviations of the mean.
99.7% of the values are within 3 standard deviations of the mean.
(a) What range of lengths covers almost all, 99.7%, of this distribution?
Those are those values within 3 standard deviations of the mean. So
From A to B, in which
The lengths from 32.1cm to 46.5cm covers 99.7% of this distribution.
Before we figure out how many customers you will need to talk per day to reach your goal, let's calculate what is 20% of how many customers you normally talk to a day.
current no. = 8
goal = 8 + 20%
20% = 8 x 0.20
(a percent is really just a fraction with the percent number over 100)
20% = 1.60
goal = 8 + 1.60
goal = 9.60
However, there is no such thing as .60 of a person so we will have to round up. You will need to talk to 10 customers per day.
The probability p of an orangecandy is 0.2. The sample size = 100.
The mean is given by:
The standard deviation is given by:
The answers are: Mean = 20. Standard deviation = 4.
