Answer:
The answer would be 2.
Step-by-step explanation:
U just subtract 39.21 -36.4= 2.81
Subtract 52 and 38
the answer is the difference between 52 and 38
-40, −20,−10,−8,−5,−4,−2,−1
First you would isolate (7m) by subtracting 4 from both sides:
4 + 7m - 4 = 5 - 4
This would leave you with:
7m = 1
Then you would isolate m by dividing both sides by 7:
7m/7 = 1/7
Your final answer:
m = 1/7
Answer: (A) H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Step-by-step explanation:
Usually null hypothesis represents the claim that the values associated to the groups being tested have no statistical difference but alternative hypothesis supports the claim that there is statistical difference.
Let
be the population mean .
We are given that the mean potassium content of a popular sports drink is listed as 140 mg in a 32-oz bottle.
i.e. Null hypothesis :
Alternative hypothesis for two tail hypothesis has sign (≠).
i.e. Alternative hypothesis : 
∴ The hypotheses for a two-tailed test of the claimed potassium content:
H0: μ = 140 mg vs. H1: μ ≠ 140 mg
