Can you post the rest of the question?
We have the mean, μ = 94 and standard deviation, σ = 10
We also have the number of samples, n = 36 and the confidence level, α = 95%
The formula for confidence interval is given
μ + z* (σ/√n) and μ - z* (σ/√n)
Where z* is the z-values for the confidence level
z* for 95% level of confidence is 1.96
Substitute this into the formula, we have
Upper limit ⇒ 94+(1.96)(10÷√36) = 94+(1.96)(10/6) = $97.27
Lower limit ⇒ 94 - (1.96)(10÷√36) = 94 - (1.96)(10/6) = $90.73
Multiply 912 x 512 x 3 = ? then divide your answer by 12 .
Answer:
y = 14 years
Step-by-step explanation:
Keesha
55000 + 2500y
Latonya
62000 + 2000y
Where,
y = number of years
Equate both expressions
55000 + 2500y = 62000 + 2000y
Collect like terms
55,000 - 62,000 = 2,000y - 2,500y
-7,000 = -500y
Divide both sides by -500
y = -7000 / -500
= 14
y = 14 years
Answer:
Option 2.
