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.

Answers

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.

the local charity receives 1/4 of funds raised during a clearance sale and Marathon. the total amount given to charity was 253.75. How much did the marathon make, if the clearance sale made 184.60?​

Answers

Answer:

The bake sale raised $412.35

Step-by-step explanation:

* Lets explain how to solve the problem

- A local Charity receives 1/3 of funds raised during a craft fair and

bake sale

∴ The total amount given to the charity = 1/3 × the funds raised during

 a craft fair and bake sale

- The total amount given to the charity was $137.45

∴ The 1/3 of of funds raised during a craft fair and bake sale is $137.45

- Lets substitute the The total amount given to the charity in the

equation above to find the funds raised during the bake sale

∴ 137.45 = 1/3 × the funds raised during the bake sale

- Multiply the both sides by 3

∴ 3 × 137.45 = the funds raised during the bake sale

∴ The funds raised during the bake sale = 412.35

* The bake sale raised $412.35

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the equation of the line is y = 10 - 2x. When the graph is plotted for the equation y = 10 - 2x it cut the x-axis at the coordinate ( 5, 0 ) and cut the y-axis at the coordinate ( 0, 10).

Solve. Dante's mom made 2 liters of cocoa. Dante and his 7 friends each drank a serving of cocoa. If each serving is 235 milliliters, how much cocoa is left?

Answers

Answer:

120 millimeters or 0.12 liters

Step-by-step explanation:

To solve this question :

we have to convert liters to millimetersmultiply the serving of coca by the number of people that consumed the cocasubtract the answer gotten from the step above from 2 litters

1 liter = 1000 millimeter

2 liters = 2 x 1000 = 2000mm

8 people drank cocoa = 8 x 235 = 1880mm

Amount of cocoa left over = 2000 - 1880 = 120mm or 0.12 liters
