Answer:
0.956
Step-by-step explanation:
X is the random variable representing the number of successes in the experiment in question;
X is represented by a binomial distribution with 5 trials and 0.18 probability of success, X~B (5, 0.18);
The probability of r successes, P(X=r), is found using the formula shown in second pic;
Working is shown in the other pic.
Answer:
C. Mean
A. The distribution is probably symmetric with a single peak.
Step-by-step explanation:
Mean measurement would give best description of the average number of car accidents people had in their lifetime. There are very less chances of skewed distribution because of the nature of the problem.
The data set in this case is not likely to have extreme variations thats why outliers wont be a problem. Therefore, mean measurement would be a better choice than median.
Example:
The typical data for this problem would look something like this.
2, 4, 4, 3, 5, 2, 1, 3
Mean= Sum of all elements/no. of elements
