Answer:
19.74% of temperatures are between 12.9°C and 14.9°C
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 question, we have that:
What proportion of temperatures are between 12.9°C and 14.9°C?
This is the pvalue of Z when X = 14.9 subtracted by the pvalue of Z when X = 12.9.
X = 14.9
has a pvalue of 0.2420
X = 12.9
has a pvalue of 0.0446
0.2420 - 0.0446 = 0.1974
19.74% of temperatures are between 12.9°C and 14.9°C
Josiah's gross pay is %152.
<u>Step-by-step explanation:</u>
It is given that, Josiah expects a paycheck of $152 for working 20 hours during his first week at a grocery shop.
But, he receives only a check of $129.48
Now, it is asked to find which amount is his gross pay. To find the gross pay, one should known the meaning of the term "gross pay" in detail.
- Gross pay is defined as the amount of money the employees receive without any deductions on taxes.
- Net pay is known as the amount of money the employees take home after all deductions is carried out from the gross pay.
Therefore, in this case, the amount Josiah expects to received without any tax deductions is $152. This is his gross pay.
Josiah was given a paycheck of $129.48 to take home after all the deductions have been done from the gross pay of $152. Thus, it can be concluded that Josiah's gross pay is %152.
