Answer:
a) Expected value of the mean = 0.793 percent
b) Standard error = 0.019 percent.
Step-by-step explanation:
Given
mean = μ = 0.793 percent
Standard deviation = σ = 0.114 percent
a) The sample mean is related to the population mean through
μₓ = μ = 0.793 percent
Hence, the expected value of the sample mean = 0.793 percent.
b) The standard error is given as
Standard error = σ/√n
where n = sample size = 36
Standard error = (0.114/√36)
Standard Error = 0.019 percent.
Hope this Helps!!!
It’s the third choice because the highest degree is three and there are three terms. FOR QUESTION 3
The first two choices for QUESTION 4
This one is a little tricky because of the conversion but .51 cm converts to roughly .2 inches (actually its .200787 but we will round to .2 for ease of math). 4 in/.2in = 20
Therefore the tree is 20 years old.
Footnote 1cm is equal to .3937 inches so it would be .51cm * .3937in = .200787in
Answer:
Step-by-step explanation:
Given,
Cost Price (CP) = Rs 460
Profit % (P%) = 5%
Now,
Profit Amount (P) = P% * CP
= ( 5/100) * Rs 460
= Rs 460/20 = Rs 23
