Answer:
48
Explanation:
(assuming these measurements are the legnth, width and height)
Volume is Length x Width x Height.
4 x 6 x 2 = 48
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 439 439 gram setting. It is believed that the machine is underfilling or overfilling the bags. A 26 26 bag sample had a mean of 443 443 grams with a variance of 225 225 . Assume the population is normally distributed. Is there sufficient evidence at the 0.01 0.01 level that the bags are underfilled or overfilled?
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.
