Answer: No, Store A is charging $2.20 per rose while Store B is charging 2.166667 dollars per rose.

Step-by-step explanation:

11/5 = 2.2

(To check) 2.2 x 5 also equals $11

However, they are not selling roses at the same rate because if you were to do 2.2x6 it will equal 13.2.

13/6 = 2.166667

Answer:

The 90% confidence interval for the percentage of people the company contacts who may buy something is between 10.82% and 14%

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 1160, \pi = \frac{144}{1160} = 0.1241$

90% confidence level

So $\alpha = 0.1$ , z is the value of Z that has a pvalue of $1 - \frac{0.1}{2} = 0.95$ , so $Z = 1.645$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1241 - 1.645\sqrt{\frac{0.1241*0.8759}{1160}} = 0.1082$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1241 + 1.645\sqrt{\frac{0.1241*0.8759}{1160}} = 0.14$

The 90% confidence interval for the percentage of people the company contacts who may buy something is between 10.82% and 14%
