Answer:
In Math, she scored in the 93rd percentile, which is higher than the French percentile. So she did better on the Math exam as compared with the other incoming college students
Step-by-step explanation:
Z-score:
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.
On which exam did she do better as compared with the other incoming college students?
On the exam for which she had the higher z-score.
Franch:
Scored 85.
Mean 72, SD = 12. So
has a pvalue of 0.8810, so her French score is in the 88th percentile.
Math:
Scored 80
Mean 68, SD = 8. So
has a pvalue of 0.9332.
In Math, she scored in the 93rd percentile, which is higher than the French percentile. So she did better on the Math exam as compared with the other incoming college students
Answer:
A. 29.91
Step-by-step explanation:
tan(x) = opposite leg / adjacent leg
tan(41) = 26 / x
0.869... = 26/x
26 / 0.869... = x
x = 29.91...
Answer:
The correct option is A.
Step-by-step explanation:
The difference between actual value and predicted value is called residual.
Formula of residual is
Where, y is observed value or actual value and is predicted value.
The value of residual is 1.4 and option A is correct.
Answer:
The correct answer would be 15.5 or C.
All of the metric systems of measurement are base 10. What this means is that for every 10 of something, you get the next level of that. For instance, 10mm = 1cm.
What the United States uses for their measurement has random bases. For instance, 12 inches = 1 foot.
