Answer:
103
Step-by-step explanation:
Answer:
A one-sided, two-sample t-test
Step-by-step explanation:
In the context, the values of the population standard deviations are not provided, therefore we have to use the two sample t tests for the difference between the two population means. This claim for the hypothesis or the alternative hypothesis is given as the average selling price is more for the first group of the sample size of 21 as compared to the other group of the sample size of 87. Therefore, we perform an one sided test or the upper tailed test.
Answer: 132
Step-by-step explanation:
Since we are informed that Group 1 of trees produced 25 percent more coconuts than Group 2 did and that Group 1 produced 165 coconuts, the number of coconuts that Group 2 produce will be:
= [100 / (100 + 25)] × 165
= 100/125 × 165
= 0.8 × 165
= 132
Group 2 produced 132 coconuts.
<h3>
Answer: -2/3</h3>
==================================================
Explanation:
Use the slope formula to find the slope of line E
m = (y2-y1)/(x2-x1)
m = (10-8)/(4-7)
m = 2/(-3)
m = -2/3
The slope of line E is -2/3
The slope of line F is also -2/3 since parallel lines have equal slopes but different y intercepts.
