Tina had $47.10 in her bank account on Monday. She withdrew $25 on Monday and also made a deposit of an amount d that she cannot
nalin [4]
The correct answer is a.  47.10 - 25 + d = 97.43.

This is because you have to subtract the $25, because it is a withdrawal, or taking out of money.
This rules out options C and D.  

Also, Tina made a deposit of an amount that she can't remember.  A deposit is adding a certain amount of money, so you have to +d.  

This rules out option B.

The only option left is option A, which makes complete sense.

nalin [4]

Answer: Option C

Step-by-step explanation:

In group(1), the risk is= 5/2000 x 100

                          = 0.25

In group(2), the risk is= 5/1000 x 100

                         = 0.5

The sample relative risk is= 0.25/0.5

                                          = 0.5

So, option C is correct.

7. License Plate Laws The Chapter Problem involved passenger cars in Connecticut and passenger cars in New York, but here we con
sergejj [24]

Yes it is true that commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars because null hypothesis is rejected.

Given among 2049 Connecticut passenger cars, 239 had only rear license plates. Among 334 Connecticut trucks, 45 had only rear license plates.

let p_{1} be the probability that commercial cars have rear license plates and p_{2} be the probability that connected trucks have rear license plates.

                         Cars                     Trucks                         Total

Total                  2049                    334                             2383

x                          239                      45                                284

p                        0.1166                   0.1347                          0.1191

α=0.05

Hypothesis will be  :

H_{0}:p_{1} =p_{2}

H_{1} :p_{1} < p_{2}

It is a left tailed test at 0.05 significance.

Standard errors of p=\sqrt{p(1-p)/n}

=\sqrt{(0.1191*0.8809)/2383}

=\sqrt{0.1049/2383}        

=0.0066

Test statistic Z=p difference/standard error

=(0.1166-0.1347)/0.0066

=-0.0181/0.0061

=-2.967

p value=0.001505<5%

Since p is less than 5% we reject null hypothesis.

We cannot calculate standard deviation so  we cannot calculate confidence interval.

Hence there is statistical evidence at 5% significance level to support that commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
