According to a recent survey, Americans get a mean of 7 hours of sleep per night. A random sample of 50 students at West Virginia University revealed the mean number of hours slept last night was 6 hours and 48 minutes. The standard deviation of the sample was 0.9 hours. Is it reasonable to conclude that students at West Virginia sleep less than the typical American? Compute the p-value

This test is left tailed that is 1 tailed.
Significance alpha = 0.05
Degrees of freedom = 50-1 = 49
Using t distribution table at alpha = 0.05 and df = 49
Critical value = -1.677
We find t test
= 6.8 - 7/(0.9/√50)
= -0.2/0.9/√50
= -1.5713
-1.5713 is greater than -1.6777 so we fail to reject the null hypothesis
Using excel p value = 0.061 which is greater than 0.05
So we conclude that college students sleep less than typical american

7) Give the equation of a line that goes through (-3,8) with a slope of 2.
Answers
Answer:
y=2x+14.
Step-by-step explanation:
1. the equation of the required line in slope-interception form is:
y=s*x+i, where s - slope, i - interception;
2. according to the condition s=2, then the required equation is:
y=2x+i;
3. if the point (-3;8) belongs to the required line, it is possible to substitute their coordinates into the required equation and calculate the value of 'i':
8=2*(-3)+i; ⇒ i=14.
4. if s=2 and i=14, then the required equation of the line is:
y=2x+14.

Answers
Answer:
x= -11
Step-by-step explanation:
17 + x = 6
Get x by itself on the left side of the equal sign by doing the opposite of (+) which is (-)
So subtract 6 - 17 = -11
So now we have:
x = -11
This is true:
17 + (-11) = 6
17 - 11 = 6
6 = 6
Answer: x = - 11

=============================================================
Explanation:
Refer to the diagram below.
Draw a line through point D such that it is perpendicular to side BC. This new line intersects BC at point E.
In other words, E is on BC such that segments DE and BC are perpendicular.
Notice how triangle CED is a right triangle with legs DE and EC. The hypotenuse is DC = 16.
Let h be the height of the trapezoid. It's also the height of triangle CED where EC is the base. In other words, h = length of DE.
--------------------------------------
Focus on triangle CED. We'll use the sine ratio to find h
sin(angle) = opposite/hypotenuse
sin(C) = DE/DC
sin(30) = h/16
0.5 = h/16
0.5*16 = h
8 = h
h = 8
The height of triangle CED is 8, so the height of the trapezoid is also 8.
--------------------------------------
Apply the area of a trapezoid formula
Area = height*(base1+base2)/2
A = h*(b1+b2)/2
A = 8*(27+21)/2
A = 8(48)/2
A = 8*24
A = 192
The trapezoid's area is 192 square units
A school has $500,000 to spend on technology. The school bought 400 laptop computers for $677 each, 20 printers for $93.49 each, and 10 scanners for $115.65 each. How much money does the school have left to spend on technology?
Answers
Answer:
500000-(400*677)-(20*93.49)-(10*115.65)=226173.7
Step-by-step explanation:
Money left 226173.7 usd
Answer:
$226,173.70
Step-by-step explanation:
400 * 677 = 270,800
20 * 93.49 = 1869.80
10 * 115.65 = 1156.50
270,800 + 1869.80 + 1156.50 = 273,826.30
500,000 - 273,826.30 = 226,173.70

I think they are all combination because order doesn't matter but I don't have a calculator with me to give you EXACT answers for all of them
Step-by-step explanation:
I think combinations because order doesn't matter; or it isn't mentioned. I could be wrong as I'm still learning and confused with finite as well. But to do these, you would do the formula of the probability of an event which is E= favorable outcome/total probabilities.. so for all men 7c6/18c6 and then do the same thing for the rest but for the right ratios and whatnot.
