We are continuing to study the difference in average time for completion for the two matching schemes. However, this time we had
IgorLugansk [536]

Answer:

We are 95% confident that the time to completion for the same color method is between 4.617 <u>less</u> to 9.383 <u>less</u> than the different color method.

Step-by-step explanation:

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

The 95% confidence for the difference in the completion time of treatment is<em> and </em>d<em> is,</em>

<em>CI</em><em> = </em>(-4.617, -9.383)

The parameter of the study is defined as:

treatment_<em>s - </em>treatment_<em>d </em>

Consider the 95% confidence interval, (-4.617, -9.383). The confidence interval consists of all negative values.

This implies that the difference between the completion time of treatment <em>s</em> and <em>d</em> is less than 0, i.e. the completion time of treatment <em>s</em> is less than that for treatment <em>d</em>.

Thus, the complete statement is:

"We are 95% confident that the time to completion for the same color method is between 4.617 <u>less</u> to 9.383 <u>less</u> than the different color method."

I need help RATS :) EHEHEHEHEHEHEEHEHEHEHEHEHEHEHEHEHEEHEHHEHEEHEHEH
galina1969 [7]

Answer:

Ok, so the answer is 3.5

Step-by-step explanation:

From what I could see it says walked for 14 around her block 4 times so your answer is 3.5 because if (Let's call her Patricia) Patricia walked around her block 4 times in 14 minutes, we have to find the unit rate, therefore we have to divide 14 by 4 as shown below

14/4=3.5

Thus your only viable solution is 3.5

Hope this Helps! Also, I would appreciate it if I could be rewarded with Brainliest, I work hard on these answers and I would enjoy it, you see my goal is to reach Genius status, as to provide many more helpful answers and help many more people. Even so, I hope that I have come of assistance to you!
