Answer:
95.64% probability that pledges are received within 40 days
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:
What is the probability that pledges are received within 40 days
This is the pvalue of Z when X = 40. So
has a pvalue of 0.9564
95.64% probability that pledges are received within 40 days

Answer:
Employers will look to see which workers are applying themselves. They want workers who are flexible, have good attitudes, are loyal to their company, practice good judgement, and are unselfish. Workers who go out and do work that is not formally assigned to them and expand the scope of their responsibilities are rewarded with promotions. Workers who maintain extensive professional networks and learn new skills are also prime candidates for promotion.
