Determine whether the observed frequencies of responses from this survey are the same as the frequencies that would be expected on the basis of the national survey. Hint: Think Chi-squared goodness-of-fit, and see Ppts and Selected Example Solutions. Can you describe a Chi-squared application, either goodness-of-fit or test-for-independence, in your profession

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
