A hypothesis test is performed to determine if the proportion of all six packs of seltzers sold in a particular grocery store ne

ar a college campus that are alcoholic exceeds 50%. A random sample of 152 customers that purchased seltzer is acquired (assume no customer purchases more than one six pack at time, alcoholic or not); the sample proportion of these purchases that are alcoholic is obtained. From this sample a test statistic of 2.60 is calculated, which has a corresponding P-value of 0.0047.Which of the following is true?
a. None of these statements is true.
b. The probability that, in a random sample of 152 customers purchasing seltzers, more than 50% of those customers will have purchased alcoholic seltzer is 0.0047.
c. The probability the null hypothesis is true is 0.0047.
d. The probability that 50% of customers purchasing seltzers will be purchasing alcoholic seltzer on any given day is 0.0047.
e. The probability the null hypothesis is true is 1-0.0047 = 0.9953.

Write a statement that why isn't 6.5 / 0.5 = 3.25
maxonik [38]

Step-by-step explanation:

6.5 / 0.5

= 6.5 / (1/2)

= 6.5 * (2/1)

= 13.

Since 13 is unequal to 3.25,

we conclude 6.5 / 0.5 = 3.25 is false.

PLEASE HELP ASAP!!!!!!!!!!!!!!

Answer:

n^{25}

Step-by-step explanation:

Hi!

So, a radical is basically a fractional power.

Square roots are numbers to the 1/2.

For example, the square root of 4 is just 4^\frac{1}{2}, or 2.

So for cube root, the 1/2 changes to a 1/3.

This can then be rewritten as n^\frac{75}{3}

or n^{25}

Multiply out and simplify to obtain a minimum sum-of-products boolean expression:
max2010maxim [7]

Answer:

As per the question, we need to convert product of sum into sum of product,

Given:

(A' +B+C')(A'+C'+D)(B'+D'),

At first, we will solve to parenthesis,

= (A'+C'+BD) (B'+D')

As per the Rule, (A+B)(A+C) = A+BC, In our case if we assume X = A'+C', then,

(A' +B+C')(A'+C'+D) = (A'+C'+B)(A'+C'+D) = (A'+C'+BD)

Now,  

= (A'+C'+BD) (B'+D') = A'B' + A'D' + C'B' +C'D' +BDB' +BDD"

As we know that AA' =  0, it mean

=A'B'+A'D'+C'B'+C'D'+D*0+B0

=A'B'+A'D'+C'B'+C'D'               as B * 0 and D*0 = 0

Finally, minimum sum of product boolean expression is

A''B'+A'D'+C'B'+C'D'

=
