Answer:
Step-by-step explanation:
Given that for a sample size of 25, sample mean = 102 lbs. and sample std deviation = 10 lbs.

(Right tailed test)
Given that we assume population is normally distributed
Test statistic:
Mean difference = +2
Std error of sample = 
t = test statistic = Mean diff/Std error 
degree of freedom
Critical value of t = 1.711
Our test statistic >1.71
Accept alternate hypothesis
Because there is significant difference between the test statistic and test statistic lies above critical value.
Answer:
Step-by-step explanation:
you need the formula (y-y1) = m(x-x1) that uses a slope and a point
m=(y1-y2)/(x2-x1)= 6-1/6+6=5/12
now pic any poit out of the 2 given ones
Answer:
(y-6) =(5/12)(x-6)
same for all the other
