Not sure about the weird echo in the question but I think we're being ask to evaluate

4 - 0.25g + 0.5h

when g=10, h=5

That's

4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 4

Clarence measures the diameter of each tennis ball and a bag with a standard ruler. Unfortunately he uses the ruler and correctl

ollegr [7]

Refer to the figure below.

Assume that there are n correct measurements
$x_{i} , \, i=1,2, \, ... \, n$
Because each measurement has an error of 0.2 in, the actual measurements are
$x_{i} + 2$

From the figure, the analysis indicates that the correct mean is
μ = 3 in = 3*2.54 cm = 7.62 cm
The correct standard deviation is
2.934 in = 2.934*2.54 cm = 7.45 cm

Answer:
μ = 7.62 cm
σ = 7.45 cm
