Answer:

994.5

Step-by-step explanation:

First, you need to figure out how many people are actually attending the event. It says that there are 50% more so we are going to have to add 56% of 150 to 150.

150 x 0.56 = 84

150 + 84 = 234

Now, we have to multiply this by 4.25, because this is the cost of the food per person.

234 x 4.25 = 994.5

A human resources representative claims that the proportion of employees earning more than $50,000 is less than 40%. To test thi

bearhunter [10]

Answer:

The statistic for this case would be:

$z=\frac{\hat p -p_o}{\sqrt{\frac{\hat p(1-\hat p)}{n}}}$

And replacing we got:

$z= \frac{0.436-0.4}{\sqrt{\frac{0.436*(1-0.436)}{700}}}= 1.92$

Step-by-step explanation:

For this case we have the following info:

$n =700$ represent the sample size

$X= 305$ represent the number of employees that earn more than 50000

$\hat p=\frac{305}{700}= 0.436$

We want to test the following hypothesis:

Nul hyp. $p \leq 0.4$

Alternative hyp : $p>0.4$

The statistic for this case would be:

$z=\frac{\hat p -p_o}{\sqrt{\frac{\hat p(1-\hat p)}{n}}}$

And replacing we got:

$z= \frac{0.436-0.4}{\sqrt{\frac{0.436*(1-0.436)}{700}}}= 1.92$

And the p value would be given by:

$p_v = P(z>1.922)= 0.0274$

tigry1 [53]

The diagonal (hypotenuse) is 13 in.

You need to use the Pythagorean Theorem

${a}^{2} + {b}^{2} = {c}^{2}$
then just plug in the numbers and solve for c.

${12}^{2} + {5}^{2} = {c}^{2}$
$\sqrt{169} = c$
13 = c
