Answer:
The required probability is 0.031918.
Step-by-step explanation:
Consider the provided information.
It is given that According to an article in The Wall Street Journal, this theory held for 22 out of the last 34 years.
Therefore n=34
The probability it is either up or down is 0.5.
Thus the value of p =0.5 and q = 0.5
Now calculate the probability
Let X is the number of years that theory held.
X has a binomial distribution with n=34 and p=0.5

Hence, the required probability is 0.031918.

The length of each interval would be 3.75 rounding to whole number is 4.
Step-by-step explanation:
- Stack in excel from lowest to highest points.
- Total number of data points are 14.
- Frequency distribution to be created.
- You can use countif function for frequency distribution.
- Since we have already got the number of intervals.
- It will be easier to calculate the number if intervals.
- normally there should be 5-15 intervals to get a better histogram.
- Basic formula is Highest data point - Lowest data point/ classes/intervals.
- So (29-14)/4 = 3.75 rounding to 4.

Answer:100
Step-by-step explanation:
This is because 2 is diagonal of 5 and they are on a graph therefore being equivalent to each other let me know if this helps
