I report if u guess or answer randomly. Which confidence level would produce the widest interval when estimating the mean of a p
kap26 [50]

Answer:

B. 61%

Step-by-step explanation:

When we have the standard deviation of a sample, we use the t-distribution.

The width of an interval is related to the margin of error, which is given by the following equation:

M = T*s

In which T is related to the confidence level(and the sample size) and s is the standard deviation of the sample. Higher confidence levels have higher values of T.

A higher margin of error means that the interval is wider. To have a higher margin of error, we desire a higher value of T, which is achieved with a higher confidence level.

So the correct answer is:

B. 61%

Arturo is
Brums [2.3K]

Answer:

<u>Yes</u>

Step-by-step explanation:

<u>When there are 2 rows</u>

  • Number of erasers per row =  No. of erasers / No. of rows
  • Number of erasers per row = 18/2
  • Number of erasers per row = 9

<u>When there are 3 rows</u>

  • Number of erasers per row =  No. of erasers / No. of rows
  • Number of erasers per row = 18/3
  • Number of erasers per row = 6

<u>Therefore, there will be more erasers per row in 2 equal rows than in 3 equal rows.</u>
