A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447.0 gram setting.
Find the solution ?So, Null hypothesis :447
It is believed that the machine is under filling the bags
So, Alternate hypothesis :
n = 41
Population standard deviation =
x = 443
We will use z test since n > 30 and we are given the population standard deviation.
Use z table to find p value
z = 443 - 447/ 21/ √41
z = - 1.2196
p value = 0.1131
α = 0.02
p value > α
So, we fail to reject null hypothesis.
So, its bag filling machine works correctly at the 447.0 gram setting.

Suppose that E and F are two events and that P(E)= 0.7 and P(FIE) = 0.3. What is P(E and F)? P(E and F) = (Simplify your answer.)
The calculated value of P(F|E) is 0.4.
Then the conditional probability that the event will occur given that has already occurred is given by the following formula:
P(B|A) = (P(A∩B)) / P(A)
Here the two events given are E and F .
P(E and F) or P(E∪F) = 0.3
and P(E)= 0.7
As per the above formula that we have already discussed, the formula can be written as:
P(F|E) = P(E ∩ F) / P(E)
P(F|E) =0.3/0.7
P(F|E) = 3/7
P(F|E) = 0.4
What in likelihood are E and F?The capital letters E and F in the discussion that follows stand in for potential experiment results, and P(E) denotes the likelihood that outcome E will be seen. The results of E or F can be listed as the results of E followed by the results of F for events that don't happen simultaneously.
How can you demonstrate the independence of two events?If knowing whether A happened has no effect on the likelihood that B will also occur, then events A and B are independent. Mathematically, the following statements are equivalent: P(A and B) = P(B A) = P(B) P(B|A) = P(B) (A).

Three of the following numbers add up to the number 31: 17, 3, 2, 19, 5.
If numbers add up, they reach the predicted total; they make sense. If the numbers don't add up, the overall sum doesn't make sense in light of the individual sums.
How to calculated numbers add up ?Only 17 + 19 - 5 = 31 can be used to "add" three of the given numbers to the number 31.
Only these sums can be created from 3 of the numbers if only positive signs are permitted.
{10, 22, 24, 24, 25, 26, 27, 38, 39, 41}
Any of these sums can be earned if either positive or negative signs are permitted.
{1, 3, 4, 5, 6, 7, 9, 10, 11, 12, 14, 15, 16, 17, 18, 19, 20, 21, 22, 24, 25, 26, 27, 31, 33, 34, 38, 39, 41}.
