Answer: 0.7471
Step-by-step explanation:
Given : The Intelligence Quotient (IQ) test scores for adults are normally distributed with a population mean of and a population standard deviation of
.
Sample size = 50
Using formula , the z-value corresponding to x=98 will be:-
Z-value corresponding to x=103 will be:-
Using the standard normal distribution table for z-scores, we have
P-value =
Hence, the probability we could select a sample of 50 adults and find that the mean of this sample is between 98 and 103 = 0.7471
Answer:
Page number 74
Step-by-step explanation:
Let
x ---> the number of days
y ---> the number of pages read
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
we have
<em>Anne</em>
The slope is equal to
The y-intercept is equal to
substitute
----> equation A
<em>Willow</em>
The slope is equal to
The y-intercept is equal to
substitute
----> equation B
equate equation A and equation B
solve for x
Find the value of y
substitute the value of x in equation A or equation B
equation A
equation B
