c. A one-tailed t statistic
Step-by-step explanation:
firstly; sample size n < 30 we use a t-test

Answer:
y = mx + b
Step-by-step explanation:
y is what the solution is, M is your slope, b is your y-intercept :)
example : -2 = 3/5 (5) - 5
y = -2 m = 3/5 x = 5 b = -5
So to do this you would add the two numbers together first. 50.6 +5.8+56.4. The length is 6 times this new amount, so you would divide it by 6 to get your answer. 56.4/6= 9.4. Therefore, the answer would be 9.4
