Answer:
1. If it is true that 60 percent of the trees in a forested region are classified as softwood, 0.015 is the probability of obtaining a population proportion greater than 0.6.
Step-by-step explanation:
Hello!
The historical information indicates that 60% of the forest trees are classified as softwood.
A botanist thinks that the proportion might be greater than 60%, so he tested his belief obtaining:
H₀: p = 0.60
H₁: p > 0.60
p-value: 0.015
You need to interpret this p-value. Little reminder:
The p-value is defined as the probability corresponding to the calculated statistic if possible under the null hypothesis. It represents the % of size n samples from a population with proportion p=p₀, which will produce a measure that provides evidence as (or stronger) than the current sample that p is not equal to p₀.
The correct answer is:
1. If it is true that 60 percent of the trees in a forested region are classified as softwood, 0.015 is the probability of obtaining a population proportion greater than 0.6.
I hope this helps!
Answer:
Step-by-step explanation:
The hour hand is 20 mm and the minute hand is
- 200% of 20 mm = 2*20 mm = 40 mm long
The tip of the hour hand travels 1/12 of the circle and the tip of the minute hand travels full circle in one hour.
Find each length and their difference using circumference formula.
<u>Hour hand</u>
- 1/12*(2*3.14*20) = 10.47 mm (rounded)
<u>Minute hand</u>
<u>The difference between the two above</u>
- 251.2 - 10.47 = 240.73 mm
Step-by-step answer:
The intersection of two sets A & B is represented by the set (collection of members) common to both sets.
A={1, 5, 7, 9, 14}
B={2, 5, 6, 8, 14, 17}
By examining the two sets, we see that the set common to both (intersection) are the numbers in bold.
