Is the following sentence a statement or not a statement? X and Y define a line

1 answer:

8 0

Yes, that's a statement. Another example of a statement is "(0,0) is the origin." Something that wouldn't be considered a statement is something like "pi is a boring and confusing number."

Hope this helps!

Eagle Outfitters is a chain of stores specializing in outdoor apparel and camping gear. They are considering a promotion that in

Zina [86]

Answer:

Step-by-step explanation:

Assuming that:

the promotion will be considered to be a success if more than 10% use the coupons received.

and coupons are sent to 100 credit card customers.

Then, the null hypothesis and alternative hypothesis is:

$\mathbf{H_o:p\le 0.10} \\ \\ \mathbf{H_a:p> 0.10}$

sample size n = 100

Using the eagle file data;

the no of people in the sample who use the coupon = 13

then,

$\hat p = \dfrac{x}{n}$

$\hat p = \dfrac{13}{100}$

$\hat p = 0.13$

Test statistics can be computed as:

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

$Z = \dfrac{0.13 - 0.10 }{\sqrt{\dfrac{0.10(1-0.10)}{100}}}$

$Z = \dfrac{0.03 }{\sqrt{\dfrac{0.09}{100}}}$

$Z = \dfrac{0.03 }{\sqrt{0.0009}}$

$Z = \dfrac{0.03 }{0.03}$

$Z = 1$

$P-value = P(Z > 1) \\ \\ P-value = 1 - P(Z < 1 ) \\ \\ P-value = 1 - 0.8413 \\ \\ P-value = 0.1587 \\ \\$

At ∝ = 0.05

Since, P-value is greater than ∝, then we fail to reject $\mathbf{H_o}$ .

Therefore, Eagle should not go with the promotion; a larger sample should be taken.
