Last year, 46% of business owners gave a holiday gift to their employees. A survey of business owners indicated that 20% plan to

alisha [4.7K]

Answer:

Part a: So the number of business owners giving holiday gift to their employees from survey is 12.

Part b: p-value is 0.00003

Part c: value of p is less that a we reject the null hypothesis.

Step-by-step explanation:

Part a

number of business owners=20% x n

number of business owners= 0.2x 60

number of business owners=12

Part b

H0: p=0.46

H1: p<0.46

Here

n=60, $\hat{p}$ =0.2, p=0.46

So test statistics is given as

$z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}\\z=\frac{0.20-0.46}{\sqrt{\frac{0.46(1-0.46)}{60}}}\\z=\frac{-0.26}{0.064}\\z=-4.04$

p-value is P(z<-4.04)= 0.00003

Part c

As value of p is less that a we reject the null hypothesis.

Wendi is selling her sculpture at an auction. The selling price goes up by $12.50 for each new bid. What is the selling price of

elena-14-01-66 [18.8K]

Answer:

Linear Equation:

y = 12.5x

This is assuming the first price is $12.50. Each new bid will add another $12.50 to it (so multiply by the amount of bids there are).

Proportional:

The amount that goes up is corresponding. This is true, for:

x = 1, y = 12.5 (x12.5)

x = 2, y = 25 (x12.5)

x = 3, y = 37.5 (x12.5)

etc. etc.

Where <em>y</em> is the selling price of sculpture:

This is true, for y stands for the total amount that it will cost the bidder.

Where <em>x</em> is the number of new bids:

<em>x</em> is the amount that of bids in all.
