Answer:
y-intercept = (0,4)
Step-by-step explanation:
To find the y-intercept, the place at which the value of x is 0, simply plug zero into your function:
f(x) = 4 - 5x
f(0) = 4 - 5(0)
f(0) = 4
Hence, the y-intercept occurs at (0,4).

Answer:
95% confidence interval for the population variance = [56.31 , 224.75].
Step-by-step explanation:
We are given that Scores on an IQ test are normally distributed. A sample of 18 IQ scores had standard deviation s = 10.
The pivotal quantity for 95% confidence interval for the population variance is given by;
~
95% confidence interval for the population variance is;
P(7.564 < < 30.19) = 0.95
P(7.564 < < 30.19) = 0.95
P( < < ) = 0.95
P( < < ) = 0.95
95% Confidence interval for = [ , ]
= [ , ]
= [ 56.31 , 224.75 ]
Therefore, 95% confidence interval for the population variance, is [ 56.31 , 224.75 ] .
Answer:
red=42 green=45 yellow=20 purple=32.
total number=121
p(that is purple)=32/121 =3.78
