Answer:
95.86% probability that the sample proportion will differ from the population proportion by less than 3%
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
For a proportion, we have that:
What is the probability that the sample proportion will differ from the population proportion by less than 3%
This is the pvalue of Z when X = 0.07 + 0.03 = 0.1 subtracted by the pvalue of Z when X = 0.07 - 0.03 = 0.04. So
X = 0.1
has a pvalue of 0.9793
X = 0.04
has a pvalue of 0.0207
0.9793 - 0.0207 = 0.9586
95.86% probability that the sample proportion will differ from the population proportion by less than 3%
12+6=18 18+18=36 total coins.
12 quarters:36 coins.
To simplify divide each side by 12.
12/12=1 36/12=3
The simplified ratio is 1:3.
Therefore the answer is B.
Hope this helps! (:
Answer:
Slope-Intercept Form of a Line (y = mx + b)
Step-by-step explanation:
The slope-intercept is the most “popular” form of a straight line. Many students find this useful because of its simplicity. One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y-intercept can easily be identified or read off from this form.
