INTERVAL ESTIMATE
4. Suppose that the amount of time spend by working student weekly is normally distributed with the standard deviation of 25 minutes. A random sample of 125 observations is drawn and the sample mean is computed as 150 minutes. Determine the 95% confidence interval estimate of the population mean.

Exercise 2. Suppose a researcher wants to estimate the mean weight of all Karate players in a tournament. He took a random sample of 30 volleybal players and ther height (in centimeters). Their weight was recorded as follows: 55 45 45 55 60 59 57 66 80 70 64 65 67 65 65 65 82 73 50 55 75 66 77 65 82 71 65 52 75 What is the mean height of the 30 volleyball players in the collegiate tournament?

state the statement is true or false the function f[x,y]={x^2y/x^4+y^2[x,y]=0 is not continuous at [0,0] and 0,[x,y]=0
ELECTROSTATICS:
Doug caught up with a rod comprising of negative(N) and positive(P) charges. He is asked to calculate the maximum net absolute value of electrostatic field possible in the region due to the rod.
Note : Assume, Electrostatic field = (absolute value of total charge) * 100;
input1 : {4,3,5}
input2 : PNP
output : (4-3+5) * 100 = 600
