Answer :
Answer:
0.6826
Step-by-step explanation:
Empirical rule states that when the a distribution is mound- shaped then the proportion of measurement falls in one standard deviation,two standard deviation, three standard deviation away from the mean are 68.26%, 95.44% and 99.73%.
We are given that mean =60 and standard deviation=14
mean-one standard deviation=60-1*14=46
mean+one standard deviation=60+1*14=60+14=74
We know that proportion of measurement falls in one standard deviation is 0.6826 or 68.26%.
Thus, proportion of measurements in the given interval. between 46 and 74 is 0.6826
