Answer:
D
Step-by-step explanation:
Lower bound of the population mean is 0.328
Upper bound of the population mean is 0.486
Confidence level is 99%
Therefore, the correct interpolation of the confidence interval is that we are 99% confident that the true value of the population mean is between 0.328 and 0.486

Answer:
Step-by-step explanation:
LHS = Sin² ∅ + Sin² ∅*tan² ∅
= Sin² ∅ [1 + tan² ∅ ] {Sec² ∅ - tan² ∅ = 1}
= Sin² ∅ *Sec² ∅
= Sin² ∅ *
= Sin² ∅ /Cos² ∅
= tan² ∅ = RHS
If we call the number "x" then:
x*25%=21
x*25/100=21
x=21*4
x=84
