A study on students drinking habits wants to determine the true average number of alcoholic drinks all UF male students have in

Butoxors [25]

Answer:

B. 97

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.025 = 0.975$ , so $z = 1.96$

Now, find M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

How many students should be sampled to be within 1 drink of the population mean with 95% probability?

This is n when $M = 1$

We know from preliminary studies that the standard deviation is around 5, so $\sigma = 5$

$M = z*\frac{\sigma}{\sqrt{n}}$

$1 = 1.96*\frac{5}{\sqrt{n}}$

$\sqrt{n} = 5*1.96$

$(\sqrt{n})^{2} = (5*1.96)^{2}$

$n = 96.04$

We round up, so the correct answer is:

B. 97

Drag each tile to the correct box. Not all tiles will be used.

Zina [86]

Answer:

$1,100 at 3.2% for 3 years -> $105.60

$990 at 3.15% for 4 years -> $124.74

$1,025 at 2.8% for 5 years -> $143.5

Step-by-step explanation:

Simple interest formula is:

A = P*(1 + r*t)

where A if final account, P is principal, r is annual interest rate (as decimal) and t is time in years

Interest earned is A - P, then:

I = P*(1 + r*t) - P = P(1 + r*t - 1) = P*r*t

If P = $1100, r = 0.032 and t = 3, then:

I = 1100*0.032*3 = $105.6

If P = $990, r = 0.0315 and t = 4, then:

I = 990*0.0315*4 = $124.74

If P = $1025, r = 0.028 and t = 5, then:

I = 1025*0.028*5 = $143.5
