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%

What it the x and y intercept of y=2x^2+3x+1
babunello [35]

x = -1

y = 1

To find this, input the equation into a graphing calculator, whether online or an actual one, and you have two options:

1 - Search for the points in which the line crosses the x and or y axis.

2 - Hit 2nd Graph to access the table and find when x and y equal zero.

Hope this helps!
