The amount of time (in minutes per day) spent on social media for a sample of 10 teens has a mean of 186.7 and a sample standard deviation of 19.99. An independent sample of 8 older adults has a mean of 93.5 minutes with a sample standard deviation of 32.01. Assume that the time spent on social media is approximately normally distributed for each group. a) Determine the value of the test statistic to test H subscript 0 colon space mu subscript t e e n end subscript equals mu subscript o l d e r end subscript against H subscript A colon space mu subscript t e e n end subscript not equal to mu subscript o l d e r end subscript. b) Determine the p-value or critical value for this test at alpha equals 0.05. c) What is your conclusion about whether the two age groups spend the same average amount of time on social media

Which of the following represents a coefficient from the expression given?
5x - 21 + x2
Answer:
1 or 5
Step-by-step explanation:
A coefficient is "a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy)".
So, in this case, the coefficient of 5x would be 5.
The coefficient of x^2 would be 1.
Hope this helps!

Use linear regression to find a
function that fits the following
points.
(0,5), (2,-13)
Answer:
Function that fits the points [tex](0,5),\,(2,-13)[/tex] is given by [tex]x+9y=45[/tex]
Step-by-step explanation:
Let [tex](x_1,y_1)=(0,5),\,(x_2,y_2)=(2,-13)[/tex]
Slope of a line joining points [tex](x_1,y_1),\,(x_2,y_2)[/tex] is given by [tex]m=\frac{x_2-x_1}{y_2-y_1}[/tex]
[tex]=\frac{2-0}{-13-5}[/tex]
[tex]=\frac{2}{-18}[/tex]
[tex]=\frac{-1}{9}[/tex]
Equation of a line joining points [tex](x_1,y_1),\,(x_2,y_2)[/tex] is given as follows:
[tex]y-y_1=m (x-x_1)[/tex]
[tex]y-5=\frac{-1}{9}(x-0)\\y-5=\frac{-1}{9}x\\9(y-5)=-x\\9y-45=-x\\x+9y=45[/tex]

A bank loaned out $15,000, part of it at the rate of 7% per year and the rest at 17% per year. If the interest received in one year totaled $2000, how much was loaned at 7%?
How much of the $15,000 did the bank loan out at 7%?
9514 1404 393
Answer:
$5,500
Step-by-step explanation:
Let x represent the quantity loaned at 7%. Then the amount loaned at 17% is (15000-x), and the total interest is ...
0.07x +0.17(15000 -x) = 2000
-0.10x = -550 . . . . . . . . . collect terms, subtract 2550
x = -550/-0.10 = 5500 . . . . divide by the coefficient of x
The bank loaned $5,500 at 7%.

Shamus owes his parents $162. He pays them 60% of the $45 he earns as a soccer referee each week. How many weeks will it take Shamus to pay back all of the money he owes his parents?
60% of 45 would be 27
He pays his parents $27 each week
Divide 162 and 27
162/27=6
It will take 6 weeks for him to pay back his parents

What is the measure of angle B in degrees?
Answer: how do I delete my answer?
Step-by-step explanation.
Here's the solution,
=》 C + 112° = 180°
( they form linear pair )
=》 C = 180° - 112°
=》C = 68°
And we know, measure of exterior angle if a triangle is equal to the sum of measures of the opposite interior angles,
So,
=》B = C + 51°
=》B = 68° + 51°
=》B = 119°
