QuestionGet an education: A survey asked 32,126 people how much confidence they had in educational institutions. The results were as follows. Round your answers to four decimal places if necessary. \begin{tabular}{lr} \hline \multicolumn{1}{c}{ Response } & Number \\ \hline A great deal & 10,022 \\ Some & 17,813 \\ Hardly any & 4291 \\ \hline Total & 32,126 \end{tabular} Send data to Excel
Part 1 of 3 (a) What is the probability that a sampled person has either a great deal or hardly any confidence in educational institutions?
The probability that a sampled person has either a great deal or hardly any confidence in educational institutions is 0.4455 .
Part: 1 / 3
Part 2 of 3 (b) Assume this is a simple random sample from a population. Use the Empirical Method to estimate the probability that a person has hardly any confidence in educational institutions.
Using the Empirical Method the probability is approximately \square .

Studdy Solution
Perform the division and round the result to four decimal places.
P(hardly any confidence)4291321260.1336 P(\text{hardly any confidence}) \approx \frac{4291}{32126} \approx 0.1336
The probability that a person has hardly any confidence in educational institutions is approximately:
0.1336 \boxed{0.1336}
