Degree of freedom = 63
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 64
Sample mean = 1400
Sample standard deviation = 240
We need to make a 95% confidence interval.
We use the t-statistic for the same.
Degree of freedom:
- It is the maximum number of logically independent values that have the freedom to vary, in the data sample.
Degree of freedom for reading the critical values of t-statistic is
Thus, the degree of freedom is 63.
