Students who attend Anytown College pay either in-state or out-of-state tuition, depending on where they reside. The mean and st

andard deviation of the sum, S, of tuition for a randomly selected pair of in-state and out-of-state students are μS = $6,348.75 and σS = $1,508.48. How can these values be interpreted? Check all that apply. The average of the sums of both types of tuitions would be $6,348.75 for many, many randomly selected pairs of students. Students who pay both types of tuition will pay $6,348.75 per semester. For a pair of randomly selected in- and out-of-state students, the sum of their tuitions is $6,348.75. For a pair of randomly selected in- and out-of-state students, the sum of their tuitions typically varies from the mean of $6,348.75 by about $1,508.48. Students who pay both in- and out-of-state tuition should expect their cost to vary by about $1,508.48 per semester.

Answer:

For a pair of randomly selected in- and out-of-state students, the sum of their tuition typically varies from the mean of $6,348.75 by about $1,508.48.

Step-by-step explanation:

Given

\mu S = \$6,348.75

\sigma S = \$1,508

Required

Interpret the standard deviations

In statistic, standard deviation is a measure of how the given data lies away (or varies) from the mean.

This implies that:

For the in-state students, the standard deviation measures how the sum of their tuition varies from 6348.75

For the out-state students, the standard deviation measures how the sum of their tuition varies from 1508

Write an equation of the parabola in vertex form. <br><br>No LINKS!!!! ​
marissa [1.9K]

9514 1404 393

Answer:

  y = -16x² +180

Step-by-step explanation:

The vertex appears to be the high point of the graph, (0, 180). Then the vertex form equation is ...

  y = a(x -0)² +180

The value of 'a' can be found using the other given point. Substituting for x and y, we have ...

  164 = a(1 -0)² +180

  -16 = a

Then the complete simplified vertex form equation is ...

  y = -16x² +180

The sum twice a number and 7, OMG I NEED HELP WITH THIS QUESTION SO I won't FAIL the test grades are due tomorrow
ZanzabumX [31]

The value of the sum of twice a number and 7 is 17.

<h3>What is an expression?</h3>

An expression is used to show the relationship between the variables that are given.

Let the number in this situation be 5. This will be illustrated as:

2n + 7

where n = number = 5

= 2n + 7

= 2(5) + 7

= 10 + 7

= 17

Therefore, the number is 17.

laila [671]

Complete Question

A survey is planned to estimate the proportion of voters who support a proposed gun control law. The estimate should be within a margin of error of ±5% with 90% confidence, and we do not have any prior knowledge about the proportion who might support the law. How many people need to be included in the sample?

Round your answer up to the nearest integer.

sample size = _____

Answer:

The sample size is n = 271    

Step-by-step explanation:

From the question we are told that  

   The margin of error is  E = 5% = 0.05

Generally given that there was no prior knowledge about the proportion of who might support the law, we will assume the sample proportion to be  

     \^ p =  0.5

From the question we are told the confidence level is  90% , hence the level of significance is    

      \alpha = (100 - 90 ) \%

=>   \alpha = 0.05

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.645

Generally the sample size is mathematically represented as  

    n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p )

=>   n = [\frac{1.645 }{0.05} ]^2 * 0.5 (1 - 0.5 )

=>   n = 271
