Answer:
101, 3, 0.025, 0.7416
Step-by-step explanation:
Given that a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101 and standard deviation equal to 12.
As per central limit theorem we have
a) Mean of sample mean =
Std deviation of sample mean =
Mean = 101
Std dev =3.00
b)
c) the probability that the sample mean deviates from the population mean μ = 101 by no more than 4.
=
$80.00 because in the ones place, 1-4 goes down and 5-9 goes up.
Answer:
B. Negative
Step-by-step explanation:
A discriminant of zero indicates that the quadratic has a repeated real number solution. A negative discriminant indicates that neither of the solutions is a real number.
You should use the formula - b+-√b^2- 4 ac/2a. A=2 B=4 C=-3. Plug these numbers into the formula.
If you get a negative in the square root try using a method called the box method.
