Answer:
y= x squared.
Step-by-step explanation:

Answer:
The parameter is the population proportion of fans who listened to her new single and has an estimated value of 90%.
Step-by-step explanation:
The parameter is a value that corresponds to a population, while an a value that corresponds to a sample is know as statistic.
She takes a sample to estimate, with a point estimate and probably with a confidence interval around this point estimate, the true proportion of fans who listened to her new single.
This is the paramater: the population proportion of fans who listened to her new single.
Its value comes from an estimation based on the sample proportion (point estimate).
The sample proportion is 90%, so we can estimate, as there is no bias, that the population proportion is also 90%.
Whenever you see of, it means times. Always multiply :) So .25 times x.
