Textbook Question

Chapter 8, Problem 29P

Estimated values of thermal conductivity of silicon at different temperatures are given in the following table.

T(K)	2	4	6	8	10	20	40	60
k(W/m-K)	46	300	820	1,560	2,300	5,000	3,500	2,100
T(K)	80	100	150	250	350	500	1,000	1,400
k(W/m-K)	1,350	900	400	190	120	75	30	20

(a) Make a plot of k versus T using log scale on both axes.

(b) Curve-fit the data vith a second-order polynomial y = ax²+ bx + C in which x = log(T) and y = log(k). Once the coefficients a, b, and c are determined, write an equation for k as a function of log(T). Use this equation for curve-fitting the data. Make a second plot that shows the data points with markers and the curve-fitted equation with a solid line.

(c) Repeat part (b) using a third-order polynomial.

A company found that the daily sales revenue of its flagship product follows a normal distribution with a mean of $4500 and a standard deviation of $450. The company defines a "high-sales day" that is, any day with sales exceeding $4800. please provide a step by step on how to get the answers in excel Q: What percentage of days can the company expect to have "high-sales days" or sales greater than $4800? Q: What is the sales revenue threshold for the bottom 10% of days? (please note that 10% refers to the probability/area under bell curve towards the lower tail of bell curve) Provide answers in the yellow cells
