17.35 Hand Size. A clever way to determine hand size in three dimensions is to measure the volume in ml of water displaced when the hand is dipped in a water container. A study used this method to gather hand volumes of 12 male college students. Here are the measurements:

400, 360, 420, 520, 460, 350, 500, 420, 450, 430, 395, 400

We consider this an SRS of all male college students. Obtain a 95% confidence interval for the mean hand size and interpret it in context.

Expert Solution

We have for given data,

Sample mean =425.42
Sample standard deviation =50.966
Sample size =12
Level of significance=1-0.95=0.05
Degree of freedom =11

t critical value is (by using t table)=   2.201

Confidence interval formula is

=(393.04 , 457.80)


Lower confidence limit=393.04

Upper confidence limit=457.80

We are 95% confident that population mean hand size is between 393.04 to 457.80

One way to determine the pH of a solution is to measure the concentration of the acid and base forms of the indicator colorimetrically. In a solution where bromocresol green (pKa = 4.66) is used as the indicator, what is the pH of the solution when the concentration ratio of the acid to base form of the indicator is 1.75.

Determine the required size (area, nominal diameter, and Bar No.) of the three reinforcing steel bars used in a 9 in. wide and 12 in. deep concrete beam to assure the beam fails in compression of the concrete and the steel reinforcement reaches its yield strength at the same load. Assume that the ultimate compressive strength of the concrete is 4,000 psi and the yield strength of the steel is 30,000 psi.
