The confidence level and sample data to find a confidence interval for estimating the population mu. round your answer to the same number of decimal places as the sample mean 88.2 < μ < 93.0.
<h3>What are the confidence level?</h3>
The confidence stage refers to the proportion of probability, or certainty, that the self-belief c language could include the real populace parameter whilst you draw a random pattern many times.
- We have this given info:
- n = 92 = pattern length xbar = 90.6 = pattern imply
- sigma =8.! = populace popular deviation
- C=99% self-assurance level
- Because n > 30 and due to the fact we recognize sigma, this permits us to apply the Z distribution (aka popular ordinary distribution).
- At 99% self-assurance, the z essential price is more or less z = 2.576 use a reference sheet, table, or calculator to decide this.
- The decrease sure of the self assurance c programming language (L) is more or less L = xbar - z*sigma/sqrt(n) L = 90.6-2.576*8.9/sqrt(92) perp= 88.209757568781 perp= 88.2
- The top sure (U) of this self assurance c programming language is more or less U = xbar + z*sigma/sqrt(n) L = 88.209757568781 L = 88.2.
- The top sure (U) of this self assurance c programming language is more or less U=xbar+z^ * sigma/sqrt(n) U = 90.6 + 2.576*8.9/sqrt(92) U = 92.990242431219
- U = 93.0.
- Therefore, the self assurance c programming language withinside the format (L, U) is about (88.2, 93.zero).

Answer:
welll if its that way it would have to be -1
Explanation:
Answer:
The correct option is;
D) Observational study
Explanation:
In an observational study, the researcher observes, notes and record the an occurrence of events which are due to the existence of a condition, test, risk factor, such that the experimental units are apparently out of the control of the researcher, or there are no researcher intervention in the study, due to either physical constraint or laid down ethics.
In the question, the researcher observes to determine the the number of people that run a light through pre recorded traffic video providing a physical restraint which makes it an observational study.
