The two intervals (114.9, 115.7) and (114.6, 116.0) are confidence intervals (computed using the same sample data) for μ = true

kenny6666 [7]

Answer:

115.3 hertz

Step-by-step explanation:

For either interval, the value of the sample mean is given by the average of the lower and upper bound of the confidence interval. Since both intervals were constructed by using the same sample, both values should be equal.

For the first interval:

$M=\frac{114.9 + 115.7}{2} \\M=115.3\ hertz$

For the second interval:

$M=\frac{114.6 + 116.0}{2} \\M=115.3\ hertz$

Answer:

U = $\frac{TE}{3}$

Step-by-step explanation:

Given

T = $\frac{3U}{E}$

Multiply both sides by E to clear the fraction

TE = 3U ( divide both sides by 3 )

$\frac{TE}{3}$ = U
