Answer:
b) 0.0007
c) 0.4163
d) 0.2375
Step-by-step explanation:
We are given the following:
We treat securities lose value as a success.
P(Security lose value) = 70% = 0.7
Then the securities lose value follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 20.
a) Assumptions
- There are 20 independent trials.
- Each trial have two possible outcome: security loose value or security does not lose value.
- The probability for success of each trial is same, p = 0.7
b) P(all 20 securities lose value)
We have to evaluate:
0.0007 is the probability that all 20 securities lose value.
c) P(at least 15 of them lose value.)
d) P(less than 5 of them gain value.)
P(gain value) = 1 - 0.7 = 0.3
Answer:
The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

the rate of growth will be 1.16
