<u>Every 18 feet.</u>
<h2>Step-by-step explanation:</h2><h3>1. Find the LCM between the numbers.</h3>LCM stands for "least common multiple", and is the least number that results from multiplicating any of the 3 numbers by another number.
Analyze numbers starting from 9 to find the LCM. The first number than can be divided by 3, 6, and 9 is 18. Hence, 18 is out LCM
<h3>2. Interpret the results.</h3>18 as a LCM means that every 18 feet there will be lights at the same distance in the circular road.

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
