suppose the returns on long term corporate bonds and T-bills are normally distributed. Based on the values below answer the foll
owing questions: what is the probability that in any given year, the return on long-term corporate bonds will be greater than 10 percent? long term corporate bonds average return= 6.30%
1 answer:
Answer:
32.35% ( the probability that in any given year, the return on long-term corporate bonds will be greater than 10 percent )
Explanation:
Given data for long-term corporate bonds
Standard deviation : 8.3%
mean = 6.2%
To calculate the probability that in any given year, the return on long-term corporate bonds will be greater than 10 percent ( USING THE NORM-DIST FUNCTION )
P( x > 10% ) = 1 - P(x<10%) = 1 - NORM-DIST (10,6.2,8.3,TRUE ) = 0.3235
= 32.35%

There were 72 (108 - 36) more maple trees in the woodlot before the bug problem. There were 108 maple trees in the woodlot before the bug problem. There are 36 maple trees in the woodlot after the bug problem.
The following information is given in the question:
Ratio of maple trees to oak trees before bug problem = 9:5
Ratio of maple trees to oak trees after replanting = 3:11
Total number of oak trees after replanting =132
Total number of trees in the woodlot is the same before and after the bug problem.
Let the number of maple trees after replanting be 'x'
From the data above, we can find the number of maple trees after replanting as follows:
So, number of maple trees after replanting in the woodlot are 36.
Let number of maple trees before bug problem be 'z'.
We can find the number of maple trees before bug problem as follows:
