20,000 = 80% of the original price so 20,000 divided by 80 = 250 then multiply that by 100 equals 250000 which is the original price

A study was conducted to compare the proportion of drivers in Boston and New York who wore seat belts while driving. Data were c
In-s [12.5K]

(A.)test statistic for this test using Ha: p8くPN is Z = -2.164 (B.) p-value (3 decimal places) is 0.015. (C.) Based on this p-value, which of the following would you expect for a 95% is negative. (D.) the correct conclusion is The proportion of Boston drivers wearing seat was significantly lower than the proportion of new York drivers wearing seat belts.

A.)

According to given data find the test statistic for this test using Ha:

p1 = 0.581

p2 = 0.832

standard error = SE = 0.116

<h3>Test statistics :-</h3>

Z = \frac{p1 - p2}{SE}

Z = \frac{0.581 - 0.832}{0.116} = -2.164

Z = -2.164

B.)

According to given Determine the p-value (3 decimal places).

<h3>p - value</h3>

it is left tailed test.

p - value for left tailed test is,

p - value = P(Z < test statistics )

p - value = P(Z < -2.164)

P - value = 0.015

C.)

Based on this p-value, which of the following would you expect for a 95%

confidence level = 95% = 0.95

significance level = α = 0.05

P -value is less than 0.05

so, reject null hypothesis at α = 0.05

That is P_{B} < P_{NY}

so, based on P - value , All values in the 95% confidence interval

PB - PNY  is negative.

D.)

According to given data What is the correct conclusion?

Reject null hypothesis at α = 0.05

so, P_{B} < P_{NY}

Hence, The proportion of Boston drivers wearing seat was significantly lower than the proportion of new York drivers wearing seat belts.

Can someone please explain number 5? please help merely if you know how to do this question
statuscvo [17]

Step-by-step explanation:

The function/equation can be rewritten to fit the variables better. C=10t+2. C stands for the total cost, and t stands for the number of tickets. The total cost of tickets is the amount of tickets ($10 each) plus another $2 (probably some kind of fee).

Find the unknown side of the triangle when x =<br> 12 in and y = 5 in.
Hatshy [7]

Answer:

13

Step-by-step explanation:

As x and y are perpendicular - we can use pythagoras.

So, The length of side x squared + The length of side y squared = The missing length squared.

12^2=144

5^2=25

144+25=169

sqrt169=13
