Suppose we want to determine if a new drug was effective at causing weight loss. To determine this, we randomly select 10 subjects, and weighed them before and after treatment. The resulting summary data for the differences is given below. Assume that the differences come from a normal distribution and the data below is based on before-after. Sample Size 10
Sample Differences Mean 6.25
Sample Differences Standard Deviation 7.52

Required:
a. Explain why we consider this paired data
b. Give the null and alternative hypotheses
c. Calculate the test statistic (Show work)
d. Using α=0.05, make a decision based on the hypotheses
e. Draw conclusions based on the real-world question

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
