The Federal Pell Grant Program gives grants to low-income undergraduate students. According to the National Postsecondary Studen

t Aid Study conducted by the U.S. Department of Education in 2008, the average Pell grant award for 2007-2008 was $2,600. We wonder if the mean amount is different this year for Pell grant recipients at San Jose State University. Suppose that we randomly select 50 Pell grant recipients from San Jose State University. For these 50 students, the mean Pell grant award is $2,450 with a standard deviation of $600. Let μ = the mean amount of Pell grant awards received by San Jose State University Pell grant recipients this year. We test the following hypotheses. LaTeX: H_0 H 0 : LaTeX: \mu=2600 μ = 2600 LaTeX: H_a H a : LaTeX: \mu\ne2600 μ ≠ 2600 The sample size is greater than 30, so a t-model is a good fit for the sampling distribution. Use this information to answer the next two questions.
What is the t-test statistic? If necessary, round to two decimal places.

What is the P-value? If necessary, round to three decimal places.

Answer:

Check the explanation

Step-by-step explanation:

According to question, sample mean xbar = 2450 with standard deviation s = 600 and sample size n = 50

population mean = 2600 (mu)

Kindly check the attached image

T- test statistic t = = 위이 1 2450 - 2600 = -150/84.85281 = -1.77

p-value = T.DIST.2T(test statistic,n-1)

where test statistic = -1.77 and n = 50

so, p-value = T.DIST.2T(-1.77,50-1) = 0.083

ESTIMATE.137,638 +52,091
OverLord2011 [107]

In order to estimate this problem we must first estimate the two numbers involved.

137,638 rounds up to 138,000.

Since the 6 is bigger than 5 it makes the number 7 round up to 8

Now..

52,091 rounds out to 52,000

Since the number to the left of the 2 is not bigger than 5 then it stays the same at 52,000

Now we have to add our estimated numbers.

138,000 + 52,000 = 190,000

Your answer is 190,000

Good Luck! :)

The slope of a line is 5 /7. What is the slope of any line that is perpendicular to that line?
Lady bird [3.3K]

Answer:

-7/5

Step-by-step explanation:

The slope of a perpendicular line is the "negative reciprocal" of the slope of the original line. so just switch the numbers and put the top number into a negative.

The formula to convert Fahrenheit to Celsius is C=5/9(F-32). Convert 30c to Fahrenheit. Round to the nearest degree
dem82 [27]

Answer:

86 degrees farenheit

Step-by-step explanation:

First, we plug 30 in for C.

Next, solve for F

Multiplying both sides by 9/5 gives us 54=F-32

Add 32 to both sides    86=F

Change to Slope-Intercept form (Y=MX+B) Show all your work!!!! 2x-y=2​
ivanzaharov [21]

Answer:

y=2x-2

Step-by-step explanation:

2x-y=2

   +y  +y      1)add y to both sides

2x=y+2

-2     -2        2) Substract 2 from both sides

2x-2=y

y=2x-2         3) Use the Refelxive POE to flip the sides

Write an expression that represents the area of the polygon shown below?
Alisiya [41]

Answer:

A = 5x + 12 (See explanation!)

Step-by-step explanation:

So, this "polygon" is really just two rectangles combined! With that in mind, remember that the area of a rectangle is base*height. Now, apply that to the problem. We know that the total length of the bottom base is 7, and 5 is the length of the second rectangle's base, so the 1st rectangle's base must be 7 - 5 = 2. The area of the 1st rectangle is then 6*2 = 12. The second rectangle's area is 5*x. So, if the area of the polygon is the sum of the two rectangles' areas, the expression you could use is:

5*x + 6* 2 = A

Simplify/Rewrite:

A = 5x + 12

(A is area, x is the unknown length in the diagram)

Hope this helps!
