A Food Marketing Institute found that 26% of households spend more than $125 a week on groceries. Assume the population proporti
on is 0.26 and a simple random sample of 380 households is selected from the population. What is the probability that the sample proportion of households spending more than $125 a week is less than 0.29?

Answer:
Discontinuity of function occurs when x = 4 or x = -4
zero of function is when x=0
Step-by-step explanation:
We are given:
Discontinuity of the function occur when the denominator is equal to zero.
So, we need to find the values of x that makes the denominator zero.
The denominator is x^2 - 16
x^2 - 16 =0
x^2 = 16
x = ± 4
So, if the value of x = 4 or value of x=-4 then the function will be discontinuous.
Zero of the function i.e f(x)=0
So, Putting the function equal to zero and finding the value of x
So, zero of function is when x=0
