The square root of 29 is 5.3851

Compare the first number. In this case, both are five, so move on to the next number.

7 is greater than 3, so the answer would be 5.7145 > The square root of 29.

Katyanochek1 [597]

Answer:

a) The confidence interval is $0.00\leq\pi_1-\pi_2\leq0.02$ .

Step-by-step explanation:

We have to calculate a confidence interval (CI) of a difference of proportions.

For the existing procedure, the proportion is:

$p_1=75/1500=0.05$

For the new procedure, the proportion is:

$p_2=80/2000=0.04$

To calculate the CI, we need to estimate the standard deviation

$s=\sqrt{\frac{p_1(1-p_1)}{n_1} +\frac{p_2(1-p_2)}{n_2} }\\\\s=\sqrt{\frac{0.05(1-0.05)}{1500} +\frac{0.04(1-0.04)}{2000} }=\sqrt{ 0.000032 + 0.000019 }=\sqrt{ 0.000051 }\\\\s=0.007$

For a 90% CI, the z-value is 1.64.

Then, the CI is:

$(p_1-p_2)-z*\sigma \leq\pi_1-\pi_2\leq(p_1-p_2)+z*\sigma \\\\(0.05-0.04)-1.64*0.007\leq\pi_1-\pi_2\leq(0.05-0.04)+1.64*0.007\\\\0.01-0.01\leq\pi_1-\pi_2\leq0.01+0.01\\\\0.00\leq\pi_1-\pi_2\leq0.02$

A digital camera costs $185 and the sales tax rate is 5.7%. What is the total cost of the camera after tax

Dovator [93]

♥ To solve find how much this will cost AFTER the price increases.
♥ Solve:
Multiply the original price as it is by: <span>1.057 (5.7 as a decimal would be 0.057, but as i said to keep the original price, the 1 will keep it there.)
</span> $185 * 1.057 = $195.545$
Final answer: <span>$195.54</span>
