The value of
Answer to Problem 14.48SE
The value of P is
Explanation of Solution
Given information:
The problem experience consists of
The number of success gets as:
No of successes | No of times obtained |
| |
| |
| |
| |
|
Calculation:
As know that,
Where,
Now, for estimating
So, consider
Put the value of
Now, the expected values for a binomial experiment of
Are
Now, for testing whether the data provide sufficient evidence to indicate there is any significance difference between actual and the experimental observations or not.
The null hypothesis is,
The alternative hypothesis is,
In case test statistic
Obs. count | Exp. count | Obs.-exp |
| |
| ||||
| ||||

|
The chi-square statistic is,
Test statistic has
The P-value can be determined as,
Thus, the value of P is
So, there is rejection of the null hypothesis because of low
Thus, the data provide sufficient evidence to indicate there is a significant difference between actual and experimental observations.
