Answer:
b
Step-by-step explanation:
We must determine the the x value at 90% confidence interval. We find this from a table relating confidence intervals and x values. For 90%, z is 1.645.
WE must determine the mean of 19 and 23:
We must determine the standard deviation. We let n be the number of population which is 2. We need to take the numbers 19 and 23 and subtract each by the mean and square the answer:
We then determine the mean of these two values as:
Now we take the square root of 365:
The standard deviation is 19.1
The answer is b
1 the equation is y=x+3 and yes y is directly proportional to x
2 the answer is c
3 the answer is c
4 the answer is b
