Given information
Here,
mean of unknown distribution =12
Standard deviation = 1,
sample size (n)= 25
Step-by-step explanation
Step 1.
The sample sum is the sum of a random sample from a population. The sample mean is the usual average of a random sample from a population: it is the sample sum, divided by the number of numbers in the sample (the sample size).
A probability distribution in which the random variable X can take on any value (is continuous). Because there are infinite values that X could assume, the probability of X taking on anyone specific value is zero. The normal distribution is one example of a continuous distribution.
