Suppose 40% of the students in a university are baseball players. If a sample of 781 students is selected, what is the probabili
3241004551 [841]

Answer:

P(p>0.43) = 0.0436

Step-by-step explanation:

Given

p = 40\% -- proportion of baseball players

n = 781 --- selected sample

Required

Determine P(p>43%)

First, calculate the z score using:

Z = \frac{\^{p}-p}{\sqrt{\frac{p(1-p)}{n}}}

This gives:

Z = \frac{48\%-40\%}{\sqrt{\frac{40\% *(1 - 40\%)}{781}}}

Convert % to decimal

Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *(1 - 0.40)}{781}}}

Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *0.60}{781}}}

Z = \frac{0.43-0.40}{\sqrt{\frac{0.24}{781}}}

Z = \frac{0.03}{\sqrt{0.00030729833}}

Z = \frac{0.03}{0.01752992669}

Z = 1.71

So:

P(p>0.43) = P(Z>1.71)

P(p>0.43) = 1 - P(Z

P(p>0.43) = 1 - 0.9564

P(p>0.43) = 0.0436

Airport offers 2 shuttles that run on different schedules.if they both leave airport at 4:00 p.m. what time will they next leave
koban [17]
 basically have to find the lowest common multiply of 6 and 9.

The LCM of 6 minutes and 9 minutes = 18 minutes

so if they both leave at 4:00 p.m., they would then both leave at 4:18 p.m.

Which expression could be a calculator’s display for the number 0.00000000000096?                                               
Zina [86]
=> 50 x 100 = 5000 <span>Expression of calculator’s display for this given number:
0.00000000000096

How to get this answer.
Since it’s a decimal number, I am pretty sure that the number will be negative.
Now, let’s move the decimal points to the right.
=> Thus the answer is c. 9.6e-13
Because, from the decimal point, we move to the right 13 times, and since it’s decimal, it’s negative. So the answer is 9.6e – 13
e represents to the number of zeros.</span>
