Answer:
decrease
Step-by-step explanation:
Given that the sample statistics gathered would not change very much for the new sample
When it is decided to take a larger sample, we find that automatically the margin of error decreases and hence confidence interval will become narrower.
When confidence level decreases then critical value decreases and hence margin of error decreases thus resulting in to decrease the confidence level,
Hence width would decrease.
i) Because of a larger sample size
ii) BEcause of decrease in confidence level.
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (2, 7)
m = 
=
Answer: V = 434cm³
6 x 10 x 5 = 300
4/3 x π x r x 4³ = 268.08257310633
268.08257310633 + 300 = 434.041286553
