Answer:
P(57 < X < 69) = 0.1513
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:
Find P(57 < X < 69):
This is the pvalue of Z when X = 69 subtracted by the pvalue of Z when X = 57. So
X = 69
has a pvalue of 0.9564
X = 57
has a pvalue of 0.8051
0.9564 - 0.8051 = 0.1513
P(57 < X < 69) = 0.1513
Answer:
When temperature is 30 in degrees Celsius then temperature in degree Fahrenheit is 86.
Step-by-step explanation:
Let C denotes the temperature in degree Celsius and F denotes the temperature in degree Fahrenheit.
According to the given question,
To convert to Fahrenheit we multiply the Celsius temperature by 9/5 and add 32.
Mathematically it can be written as,
For example , let us take the temperature in mexico to be 30 degrees Celsius to convert the temperature to Fahrenheit we can use this equation as ,
Put C = 30, we get
Thus, when temperature is 30 in degrees Celsius then temperature in degree Fahrenheit is 86.
