Null: the mean amount of peanut butter in a jar is equal to 32 oz.
alternative: the mean amount of peanut butter in a Jar is less than 32oz.
type 1 error is is rejecting the null when it is actually true. this means that we would say that the mean amount of peanut butter is not equal to 32 when it actually is.
type 2 error is failing to reject the null when it is actually false. this means that we would say the mean amount of peanut butter is equal to 32 when in reality it is less.
Step-by-step explanation:
{0,1,2,3,4,5,6,7,8,9}--set of numbers from 0 to 9
{2,3,5,7}---set of prime numbers from 0 tp 9
there are 10 numbers in the first set and 4 numbers in the second set.
4/9 is the probability that the digit he selects is a prime number
Hope that helps :)
Remember you can do anything to an equation as long as you do it to both sides
4x-5=4x+10
minus 4x both sides
-5=10
false

Answer:
Step-by-step explanation:
Problem 4a
You have 6 numbers on the cube, a bag with 4 letters and a spinner with 3 letters
The total number of results is
6 * 4 * 3 = 72
Problem 4b
P(A,3,Q) = (1/3)(1/6)(1/4) = 1/72
Problem 4c
A and Q remain the same. 1/3 and 1/4
Not rolling a 6 is a little different. Success will result in a 1 2 3 4 5 being thrown. That's 5/6
So the results are 1/3 * 1/4 * 5/6 = 5/72
