Answer:
around 88
times 5 11 times to get 55 so times 8 11 times for approximate answer
Solution :
Given :
Sample mean,
Sample size, n = 40
Standard deviation, s = 83.2
∴ The null hypothesis is
Alternate hypothesis is
Test statistic :
z = 0.813
Now at α = 0.05, for a right tailed,
Since, , we fail to reject the null hypothesis.
Answer:
28
Step-by-step explanation:
Degrees of freedom is defined as the number of independent values or quantities which can be assigned to a statistical distribution.
#In a two sample study, the t-statistic degrees of freedom is calculated as
#Where denotes the sample size of the sample.
The t-statistic degrees of freedom is thus 28
