Answer:
There is not enough evidence to support the claim that union membership increased.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 400
p = 11.3% = 0.113
Alpha, α = 0.05
Number of women belonging to union , x = 52
First, we design the null and the alternate hypothesis

The null hypothesis sates that 11.3% of U.S. workers belong to union and the alternate hypothesis states that there is a increase in union membership.
Formula:


Putting the values, we get,

now, we calculate the p-value from the table.
P-value = 0.141636
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Thus, there is not enough evidence to support the claim that union membership increased.
Your answer is going to be B.
Answer:
Step-by-step explanation:
A binomial distribution as the name indicates two possible outcomes.
This procedure does not result in binomial distribution.
Conditions not met is that a binomial distribution only works when there are two choices available. And 7777 is not evenly divisible by 2.
(A) The cost would be $6,600 because 100 guests would be $35 * 100 which is $3,500. Then, add that amount to the cost of the venue. $3,100 + $3,500 = $6,600.
(B) C = $3,100 + (n - 50) * 35
(C) 118 guests
