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?​

B.  Let p and q be propositions

p: You make a correct program

q: You get an A

Write each of the following sentences in terms of p, q and logical connectives:

______________1. You do not make a correct program.

______________2. You make a correct program, but you do not get an A.

______________3. Making a correct program is sufficient for getting an A.

______________4. You get an A but you do not make a correct program.

______________5. Whenever you get an A, you are making a correct program.

A.         Let p and q be propositions

p: 4 is an even integer

q: 5 is an odd integer

Write each of the following sentences in terms of p, q and logical connectives:

______________1. 4 is an even integer and 5 is an odd integer.

______________2. 4 is not an even integer or 5 is an odd integer.

______________3. If 4 is an even integer then 5 is an odd integer.

______________4. 4 is an even integer whenever 5 is an odd integer.

______________5. 4 is not an even integer if an only if 5 is not an odd integer.

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

Use the bissection method to approximate the root of f(x)=2x²-1 in the interval . Let ε=0.1 be the margin of error of approximation.
