Answer:


Step-by-step explanation:
Given


Solving (a); Point estimate of mean
To do this, we simply calculate the sample mean




Solving (b); Point estimate of standard deviation
To do this, we simply calculate the sample standard deviation





<em>Note that: The sample mean and the sample standard deviation are the best point estimators for the mean and the standard deviation, respectively.</em>
<em>Hence, the need to solve for sample mean and sample standard deviation</em>
