The number 70 is decreased to 41. What is the percentage by which the number was decreased, to the nearest tenth of a percent?
Answer:
Decreased percent = 41.4 % (Approx.)
Step-by-step explanation:
Given:
Old number = 70
New number = 41
Find:
Decreased percent
Computation:
Decreased number = 70 - 41
Decreased number = 29
Decreased percent = [29 / 70]100
Decreased percent = 41.42%
Decreased percent = 41.4 % (Approx.)
A student wants to compare the mean times needed to access flight information for two major airlines. 20 randomly selected students accessed one airline's Web site, and the time required to locate the flight information had a mean of 2.5 minutes and a standard deviation of 0.8 minute. 20 different randomly selected students accessed the other airline's Website, and the time required to locate the flight information on that site had a mean of 2.1 minutes and a standard deviation of 1.1 minutes. Assuming that the conditions for inference are met, which of the following statements about the p-value is true?A. The p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two WebsitesB. The p-value is greater than 0.01 but less than 0.05; therefore, there is a significant difference in mean search times on the two WebsitesC. The p-value is greater than 0.05 but less than 0.10; therefore, there is a significant difference in mean search times on the two WebsitesD. The p-value is greater than 0.10; therefore, there is no significant difference in mean search times on the two WebsitesE. Since this is a matched-pairs situation, additional information is needed to perform a test of significance.
Answer:
The statement which can be true about the p-value is;
A. The p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two Websites
Step-by-step explanation:
Whereby the p-value is less than the significance level or pre-defined number we reject the null hypothesis that there is no difference in the mean time it takes to access the Websites of the two major airlines
Where the p-value is larger than the significant level, we fail to reject the null hypothesis and therefore, there is not enough evidence to indicate that the mean time to access the Websites of the two major airlines are different
The p-value is compared with a given level for the test, for it to be assed
The option that has the correct inference based on only one significant level or predefined is the p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two Websites
The statement which can be true about the p-value is (A).
A. The p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two Websites
What is the p-value?
The p-value in statistics is the likelihood of getting outcomes at least as severe as the observed results of a statistical hypothesis test, given the null hypothesis is valid.
The reason for option A is correct.
We reject the null hypothesis that there is no difference in the meantime it takes to visit the Websites of the two main airlines when the p-value is less than the significance level or pre-defined number.
We fail to reject the null hypothesis when the p-value is greater than the significant threshold
Hence there is insufficient evidence to suggest that the meantime to visit the websites of the two main airlines is different.
For the test to be assessed, the p-value is compared to a predefined level.
The p-value is less than 0.01 in the option that has the accurate inference based on only one significant level or predetermined; hence, there is a considerable difference in mean search times.

Leo is running a 5% mile race. It took him 2 minutes to run the first mile of the race. If Leo continues running at the
same pace, how many more minutes will it take him to finish the race?
Answer:
8 minutes
Step-by-step explanation:
Leo has already run 1 mile, leaving him with 4 more to finish the race. At 2 minutes a mile (a ridiculously impressive pace, considering the world record mile time is just a little under 3:45), it will then take him 4 x 2 = 8 minutes to cross the finish line.

Given:
The dimensions of a box are 3ft, 3ft and 13 ft.
To find:
The length of the longest flagpole that could be shipped inside the box.
Solution:
We know that the length of longest flagpole that could be shipped inside the box is equal to the length of the diagonal.
[tex]Diagonal=\sqrt{l^2+b^2+h^2}[/tex]
Where, l is length, b is breadth and h is height.
[tex]Diagonal=\sqrt{(3)^2+(3)^2+(13)^2}[/tex]
[tex]Diagonal=\sqrt{9+9+169}[/tex]
[tex]Diagonal=\sqrt{187}[/tex]
[tex]Diagonal\approx 13.67[/tex]
Therefore, the longest flagpole that could be shipped is about 13.67 feet long.
