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%.
Answer:
The answer is 127.32
Step-by-step explanation:
400= Pi multiplied Diameter
D= 400/Pi= 127.32
Answer:
D: 6y+3+5y-2
Step-by-step explanation:
6y+3+5y-2 = 11y + 1
All the other expressions evaluate, after simplification to 11y+5
The percentage decrease is 16.667%
72-60=12
12/72 =0.166
0.1666×100%
16.667%
