Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 206 mg
Sample mean, 
= 217.5 mg
Sample size, n = 14
Sample standard deviation, s = 14.9 mg
Claim:
The mean sodium content for the sports drink is not 206 mg. It is different than 206 mg.
Thus, we design the null and the alternate hypothesis
We use two-tailed t test to perform this hypothesis.
51/2 = 25.5
11/5 = 2.2
25.5 + 2.2 = 27.7 or 27 7/10
Answer:
The independent variable is number of minutes and the dependent variable is number of miles. Constant of proportionality is 1.2 because 9.6/8=1.2 and 18/15=1.2
Step-by-step explanation:
Answer:
P(green or orange) = 4/7
Step-by-step explanation:
We need to know how many tennis balls there are
total = 15 yellow+ 5 orange+ 15 green
= 35 balls
Probability of green or orange tennis ball is the sum of the green and orange tennis balls over the total balls
P(green or orange) = (green + orange)/total
= (15+5)/35
=20/35
=4/7
