Answer:
896
Step-by-step explanation:
14 of 20 teens eats breakfast every morning.
The percentage of those who eat breakfast every morning
= 14/20 x 100%
= 0.7 x 100%
= 70%
So, 70% of 20 teens eat breakfast every morning.
The reasonable prediction for the number of teens that eats breakfast every morning from 1280 teens will be 70% of 1280.
70/100 x 1280
0.7 x 1280
896
The prediction would be 896 out of 1280 teens eats breakfast every morning

Answer:
They spend at least 69.48 minutes reading the paper.
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:

For the 10% who spend the most time reading the paper, how much time do they spend?
They spend at least X minutes, in which X is the value of X when Z has a pvalue of 0.90. So it is X when Z = 1.28.




They spend at least 69.48 minutes reading the paper.
