Answer:
The standard deviation of weight for this species of cockroaches is 4.62.
Step-by-step explanation:
Given : A different species of cockroach has weights that are approximately Normally distributed with a mean of 50 grams. After measuring the weights of many of these cockroaches, a lab assistant reports that 14% of the cockroaches weigh more than 55 grams.
To find : What is the approximate standard deviation of weight for this species of cockroaches?
Solution :
We have given,
Mean
The sample mean x=55
A lab assistant reports that 14% of the cockroaches weigh more than 55 grams.
i.e. P(X>55)=14%=0.14
The total probability needs to sum up to 1,
The z-score value of 0.86 using z-score table is z=1.08.
Applying z-score formula,
Where, is standard deviation
Substitute the values,
The standard deviation of weight for this species of cockroaches is 4.62.
Simple...
you have:
1.) Find the slope of the line using (-2,1) and (3,6)
Using
m=1 (slope)
2.)Tell whether the equation, 8y+3=5x+3, is a direct variation.
y=
(None)
3.)What is the slope and y-intercept of the graph of the equation y=2x+3?
Slope =2
y-intercept=3
C.
Thus, your answer.
