A spinner has three unequal sections.
Red = 10
Yellow = 14
Blue = 6
We are asked to find the experimental probability of landing on yellow.
Recall that the experimental probability is given by
In this case, the number of desired outcomes are
Yellow = 14
The total number of possible outcomes is
Total sections = 30
Therefore, the experimental probability of landing on yellow is 7/15
Answer:
That's your answer
Answer:
we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
Step-by-step explanation:
The estimated proportion of interest is
We need to find a critical value for the confidence interval using the normla standard distributon. For this case we have 95% of confidence, then the significance level would be given by and
.
And the critical value is:
The confidence interval for the true population proportion is interest is given by this formula:
Replacing the values provided we got:
And we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
