A weight-loss program claims that, on average, participants lose 10 pounds during the first month of participation. An independent organization constructed a 95% confidence interval of (6.63 , 9.15) for the average amount of weight lost during the first month of this program. What conclusion best evaluates the claim made about this program’s effectiveness?

For this case since the confidence interval not contains the value 0 we can conclude that we have a significant effect in terms of the loss weight since the confidence interval just show positive values, this conclusion can be made at a significance of 5%

Step-by-step explanation:

For this case we know that the confidence interval for the weight loss program is given by:

For this case since the confidence interval not contains the value 0 we can conclude that we have a significant effect in terms of the loss weight since the confidence interval just show positive values, this conclusion can be made at a significance of 5%

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
