Not sure if that is the entire question, but yes, it does. Poly comes from the Greek polus or polloi meaning much or many.
If you're looking just to enter the numbers from the first row but in the hundredths place
Category 1 will be .30

The answer would be 13.9 kg of gravel used per square meter
Answer:
Plot 2 2/5 at the 4th tick mark past 2
Plot 1 7/10 at the 7th tick mark past 1
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 12
For the alternative hypothesis,
µ < 12
Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = population standard deviation
n = number of samples
From the information given,
µ = 12 minutes
x = 8 minutes
σ = 12 minutes
n = 36
z = (8 - 12)/(12/√36) = - 4/2 = - 2
Test statistic = - 2
