Answer:
Mean and standard deviation of the sample mean are 225.8 and 3.56 respectively.
Step-by-step explanation:
The mean (μₓ) and standard deviation of the sample mean (σₓ) are related to the mean (μ) and standard deviation of the population (σ) through the following relationship
μₓ = μ = 225.8
σₓ = σ/√n = 17.8/√25 = 17.8/5 = 3.56
Use a centimeter ruler to find<span> the </span>map distance<span> from Charlotte to Winston-Salem. The </span>map distance<span> is about 1.6 cm. Use a proportion to </span>find the actual distance<span>. Let n represent the </span>actual distance<span>.</span>
11.45 • 38 + 11.45/4 = $437.97
Distance
|a+bi| is the length of the vector from origin to (a,b).
