The U.S. Bureau of Labor Statistics reports that 11.3% of U.S. workers belong to unions (BLS website, January 2014). Suppose a s
vitfil [10]

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

H_{0}: p = 0.113\\H_A: p > 0.113

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:

\hat{p} = \dfrac{x}{n} = \dfrac{52}{400} = 0.13

z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

Putting the values, we get,

z = \displaystyle\frac{0.13-0.113}{\sqrt{\frac{0.113(1-0.113)}{400}}} = 1.073

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.

Determine whether or not the given procedure results in a binomial distribution. If not, identify which condition is not met. Sp
laila [671]

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.

How do I solve this ?
dedylja [7]

(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
