You are thinking of using a t procedure to construct a 95% confidence interval for the mean of a population. you suspect the distribution of the population is skewed with outliers. which of the following statements is correct?
a. you should not use the t procedure because the population does not have a normal distribution.
b. you may use the t procedure, provided your sample size is large, say at least 40.
c. you may use the t procedure because it is robust to nonnormality.

rx and sx

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
