Answer:
True
Explanation:
The statement is true.
Suppose a consumer purchases a bundle of goods, say 40 units with his given money income of $1000.
Now, if there is a fall in the price level of the goods then this will increase the purchasing power of the consumer and hence he will be able to buy more quantity of goods, say 60 units with the same level of money income i.e $1,000.
This illustrates that as the price level falls, the purchasing power of the consumer increases or we can say that holders of money become richer.

Answer:
The manufacturer should announce a guaranteed mileage of 44528 miles
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 guaranteed mileage should the manufacturer announce
Only until the 5th percentile will have to be replaced, which is the value of X when Z has a pvalue of 0.05. So it is X when Z = -1.645.




The manufacturer should announce a guaranteed mileage of 44528 miles
