Use k = 8.99 × e+9 N·m²/C², ε₀ = 8.85 × e-12 C²/(N·m²), e = 1.60 × e-19 C. Three point charges are fixed in place: +[a] μC at the origin, −[b] μC at ([x] m, 0), and +[c] μC at (0, [y] m). What is the magnitude of the net electric force on the +[a] μC charge, in N? Q10_formula_figure.png

A random sample of 16 passenger fares on Amtrak between Chicago and Denver resulted in a mean fare of $180 and a standard deviation of $40. We are interested in estimating the Confidence Interval on the true “Population Mean” fare between Chicago and Denver on Amtrak. Based on the problem description, Which probability distribution should you use in computing the “Margin of Error” in the Confidence Interval Estimation on Population Mean?

A random sample of 16 passenger fares on Amtrak between Chicago and Denver resulted in a mean fare of $180 and a standard deviation of $40. We are interested in estimating the Confidence Interval on the true “Population Mean” fare between Chicago and Denver on Amtrak. If we want to develop a 94% Confidence Interval estimate on the “Population Mean” fares between Chicago and Denver on Amtrak, which Excel function (among the following) will give us the correct “Margin of Error” value directly?

A travel agency reported that amount spent per day per person at a vacation destination follows a Normal distribution with a standard deviation of $235 and an average of $979. We want to find the amount (in $), assuming the spending is in the lower 30% of per day per person spending distribution at the vacation destination. What is the correct Excel formula (among the ones listed below) that will help us find the answer?
