The usher at a wedding asked each of the 80 guests whether they were a friend of the bride or of the groom. Here are the results
Artyom0805 [142]

Answer: P(B|G) = 3/5 = 0.6

the probability that the guest is the friend of bride, P(bride | groom) is 0.6

Complete Question:

The usher at a wedding asked each of the 80 guests whether they werea friend of the bride or of the groom. The results are: 59 for Bride, 50 for Groom, 30 for both. Given that the randomly chosen guest is the friend of groom, what is the probability that the guest is the friend of bride, P (bride | groom)

Step-by-step explanation:

The conditional probability P(B|G), which is the probability that a guest selected at random who is a friend of the groom is a friend of the bride can be written as;

P(B|G) = P(B∩G)/P(G)

P(G) the probability that a guest selected at random is a friend of the groom.

P(G) = number of groom's friends/total number of guests sample

P(G) = 50/80

P(B∩G) = the probability that a guest selected at random is a friend is a friend of both the bride and the groom.

P(B∩G) = number of guests that are friends of both/total number of sample guest

P(B∩G) = 30/80

Therefore,

P(B|G) = (30/80)/(50/80) = 30/50

P(B|G) = 3/5 = 0.6

A production line operation is designed to fill cartons with laundry detergent to a mean weight of 32 ounces. A sample of carton
Solnce55 [7]

Answer:

There is no significant evidence to conclude that the mean weight of laundry detergent is being underfilled or overfilled.

Step-by-step explanation:

The null hypothesis ; H0 : μ = 32

The alternative hypothesis : H1 : μ ≠ 32

The null hypothesis is the initial truth statement, therefore, when the Null hypothesis cannot be rejected, the conclusion goes thus :

There is no significant evidence to conclude that there is difference in the mean weight of laundry detergent. Hence, detergent is neither being underfilled or overfilled.

Select from the drop-down menus to correctly complete the statement. The expressions 3.22 1 and 10 – 0.33 . 2 should be joined b
ANTONII [103]

we have the expressions

3.2^2-1=10.24-1=9.24

10-0.33*2=10-0.66=9.34

therefore

should be joined by a not equal sign to form an inequality

so

9.24 < 9.34

9.24 is less than 9.34

I’ve completed the question.

Would you like me to elaborate on any point?
