The answer is "".
Step-by-step explanation:
Please find the complete question in the attached file.
We select a sample size n from the confidence interval with the mean and default
, then the mean take seriously given as the straight line with a z score given by the confidence interval
Using formula:
The probability that perhaps the mean shells length of the sample is over 4.03 pounds is
Now, we utilize z to get the likelihood, and we use the Excel function for a more exact distribution
the required probability:
The theoretical probability that Chandra will be chosen as one of the science fair participants is 0.8 or 80%.
<h3>What is theoretical probability?</h3>Theoretical probability of an event is the ratio of number of favourable outcome to the total expected number of outcome of that event.
Five students, Adriana, Ben, Chandra, Diana, and Ernesto, would each like one of the four spots at the regional science fair.
Their names are placed in a hat, and four names are chosen at random to decide who attends the fair.
- The total number of names are 5.
- The total number of names chosen are 4.
The total number of ways 4 names can be taken out from 5 names is,
.
Here one spot needs to be fixed for Chandra. Now the total number of outcome remain 4 and favourable outcome remain 3.
Thus, the number of ways 4 names can be taken out such that it contains the name Chandra is
.
The theoretical probability that Chandra will be chosen as one of the science fair participants is,
Thus, the theoretical probability that Chandra will be chosen as one of the science fair participants is 0.8 or 80%.
