Answer: mean of sampling distribution of means = 18.6
Step-by-step explanation:
In sampling theory, the population mean is expected to equal to the mean of sampling distribution of means if the estimator is to be a good representative of the population. so, on this note, the mean of sample distribution of means is equal to the population mean = 18.6
Answer:pythagoream theorem applies to right angle triangle.
Formula
C^2= a^2 + b^ 2
Where a&b are the two sides of the triangle so we need to find side c.
C^2 = 35.42^2+ 21.64^2
C^2 = 1254.57 + 468.29
C^2 = 1722.86
C = square root of 1722.86
C= 41.51m
Area of triangle
A = ab/2
A = 35.42 x 21.64/2
A = 383.24.
