,, yes the confidence interval only contains positive values
Answer:
Yes, the confidence interval only contains positive values.
Step-by-step explanation:
A 98% confidence interval for the mean difference (after – before) in score is 137.04 points to 248.96 points.
Based on the confidence interval if we go though the table we will find that each student show increase in confidence level .
As, At least the confidence level improved because it contains positive values only if we subtract previous value with the new values.
Therefore ,Yes, the confidence interval only contains positive values.

Through extensive data collection, quality control experts have verified that the true mean weight of a wrapped Starburst candy is 5.1 grams, as advertised on the package. However, in a class activity where you selected and weighed 8 wrapped Starburst candies you obtained a p-value of 0.003 and concluded that the true mean weight of Starburst candies is not as advertised. What type of error was potentially made in this hypothesis test
Answer:
Type 1 error.
Step-by-step explanation:
H0 : μ = 5.1
H1 : μ ≠ 5.1
The Pvalue of the test = 0.003
Decision made by the researcher was conclude that mean weight is not as advertised, that is the researcher rejected the Null hypothesis.
However, when the Pvalue is < α - value , we reject the null ; The type of error the researcher could have made is that ; The mean weight may be truly as advertised, Hence, leading us to make a false positive error, thus is rejecting a true null. This is a TYPE 1 error.

Answer:
As per dot plots we see the distribution of prices is close but majority of prices are concentrated in different zones. So MAD would be more similar by the look.
Let's verify
Neighborhood 1Data
55, 55, 60, 60, 70, 80, 80, 80, 90, 120Mean
(55*2+ 60*2+ 70+ 80*3 + 90+ 120)/10 = 75MAD
(20*2+15*2+5+5*3+15+45)/10 = 15Neighborhood 2Data
100, 110, 110, 110, 120, 120, 120, 140, 150, 160Mean
(100 + 110*3+ 120*3+ 140 + 150+ 160)/10 = 124MAD
(24+14*3+4*3+16*3+16+26+36)/10 = 20.4As we see the means are too different (75 vs 124) than MADs (15 vs 20.4).

Step-by-step explanation:
A company produces remote-controlled helicopters. The company’s profit, in thousands of dollars, as a function of the number of helicopters produced per week can be modeled by a quadratic function. When 1 helicopter is produced per week, the company’s profit is 4 thousand dollars. The maximum profit, 22 thousand dollars, occurs when 4 helicopters are produced per week.
The function that models the scenario, where h is the number of helicopters produced per week, is
f(h) = –2(h – 4)2 + 22.
When 6 helicopters are produced weekly, the company’s profit is (blank)
thousand dollars.

Solve the system of linear equations by substitution.
x-2y=6
3x-5y=11
Answer:
x = -8, y = -7
Step-by-step explanation:
=> x = 6 + 2y
substitute x = 6 + 2y into the equation 3x - 5y = 11 to solve for y:
=> 3(6 + 2y) - 5y = 11
=> 18 + 6y -5y = 11
=> y = -7
substitute y = -7 into the equation x - 2y = 6 to solve for x:
=> x - 2(-7) = 6
=> x +14 = 6
=> x = -8

During the lunar cycle, the Moon always appears: A. to wax, but not wane. B. to wane, but not wax. C. to wax, then wane. D. to wane while waxing. Please help!
Answer:
C.to wax then wane
Step-by-step explanation:
Waxing is "Maxing," or growing with light until a full moon is reached. Waning is the opposite, or decreasing after a full moon, and is always illuminated on the left. Then, there is a waxing or waning Gibbous moon, which means more than half of the moon is illuminated.

John went to his baseball game. His mom dropped him off at 4:40 pm and he left his game at 7:50 pm. How long was John at his game?
Answer:
I got 3 hours and 10 minutes
Step-by-step explanation:
If you continuously add numbers in decimal form you will find the answer also.
But also another way in order to find a time answer you could also subtract
7.50-4.40= 3.10
or just 3.1 in this case.
But in a time frame always add the 0 to it.
So 3 hours and 10 minutes!
