A study assessed the effects of playing a computer game (solitaire) during lunch on behavioral and physiological variables. A sample of 44 healthy adults was randomly assigned to eat lunch either with the computer game distraction or without distraction. The food served for lunch was exactly the same for everyone. All participants also had the same breakfast. Thirty minutes after lunch, participants were offered cookies as a snack and were instructed to eat as many or as few cookies as they liked. Here are the summary statistics for the findings:25
Group n X Distraction 22 52.1 45.1 No distraction 22 27.1 26.4
(a) Do the findings support the hypothesis of greater snack the two-sample t statistic and P-value, and conclude
(b) Can you conclude that distraction during meals causes intake after meals taken with a distraction? State hypotheses in terms of the two population means, obtain using a significance level of 0.05 the greater snack intake? Explain your reasoning.
Answers
Answer:
H0 : μD = μN
H0 : μD > μN
Test statistic = 2.192
Pvalue = 0.017
there is strong evidence that healthy adult eat more cookies for a snack when they are distracted with a computer game during lunch than when they are not.
Step-by-step explanation:
Given the data:
n1 = 22 ; x1 = 52.1 ; s1 = 45.1
n2 = 22 ; x2 = 27.1 ; s2 = 26.4
H0 : μD = μN
H0 : μD > μN
The test statistic :
(x1 - x2) ÷ (Sp*√(1/n1 + 1/n2))
Sp = (n1 - 1)s1² + (n2 - 1)s2²] ÷ (n1 + n2 - 2)
Sp = √[((21 * 45.1^2) + (21 * 26.4^2)) ÷ 42]
Sp = 36.952469
Test statistic :
(52.1 - 27.1) ÷ Sp * √(1/21 + 1/21))
25 ÷ (36.952469 * 0.3086066)
25 ÷ 11.4037758196954
Test statistic = 2.192
Using the Pvalue from Test statistic calculator :df = 42, Tscore = 2.192
Pvalue = 0.017
α = 0.05
Pvalue < α
Hence, there is strong evidence that healthy adult eat more cookies for a snack when they are distracted with a computer game during lunch than when they are not.

Use the method of cylidrincal shells to find the volume of the solid generated by rotating the region bounded by the curves y=6x-2x^2 and y=x^2 about the y axis.
Answers
Find where the two curves intersect:
y = 6x - 2x ²
y = x ²
6x - 2x ² = x ² → 3x ² - 6x = 3x (x - 2) = 0 → x = 0 and x = 2
Now, for a shell of radius x units away from the axis of revolution, the height of the shell would be the vertical distance between the upper curve and the lower curve. For 0 ≤ x ≤ 2, we have 6x - x ² ≥ x ², so the height of any given shell is (6x - x ²) - x ² = 6x - 2x ².
Then volume of the solid is
[tex]\displaystyle 2\pi \int_0^2 x(6x-2x^2)\,\mathrm dx = 2\pi \left(2x^3-\frac{x^4}2\right)\bigg|_0^2 = \boxed{16\pi}[/tex]

Answers
Answer: B
Step-by-step explanation:
The height of the actual tree when on a scale drawing with a scale of 1 cm:0.75 ft, the height of a mailbox is 6.5 cm, is 4.875 ft.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
On a scale drawing with a scale of 1 cm:0.75 ft, the height of a mailbox is 6.5 cm. Here, the scale factor is,
[tex]k=\dfrac{1\rm\; cm}{0.75\rm\; ft}[/tex]
The height of a mailbox is 6.5 cm. Let suppose, the actual tree is x meter long. Thus, the ratio of this factor is,
[tex]k=\dfrac{6.5}{x}[/tex]
Comparing both factors,
[tex]\dfrac{1\rm\; cm}{0.75\rm\; ft}=\dfrac{6.5}{x}\\x=6.5\times0.75\\x=4.875[/tex]
Thus, the height of the actual tree when on a scale drawing with a scale of 1 cm:0.75 ft, the height of a mailbox is 6.5 cm, is 4.875 ft.

Answer:
C. Solving this equation results in the statement -48 = 48. Because this is a false statement, the equation has no solution.
Step-by-step explanation:
8(3x - 6) = 6(4x + 8)
24x - 48 = 24x + 48
minus 24x from both sides and you get -48 = 48
A false statement means one side does not equal the other. False statement always means no solution
you can solve this equation for x, but looking at the answers it's not what the question is asking for
