Answer:
t distribution behaves like standard normal distribution as the number of freedom increases.
Step-by-step explanation:
The question is missing. I will give a general information on t distribution.
t-distribution is used instead of normal distribution when the <em>sample size is small (usually smaller than 30) </em>or <em>population standard deviation is unknown</em>.
Degrees of freedom is the number of values in a sample that are free to vary. As the number of degrees of freedom for a t-distribution increases, the distribution looks more like normal distribution and follows the same characteristics.
216 ? Maybe . I think you have to multiply 81 times .375 you move the decimal two places over . I believe that’s how you do the problem
Um... I think you meant <span>24:96 = 5:x
In that case, x=20
</span>
X=2.6
