Final Answer:
The indicated probability
for a normal distribution with a specified mean and standard deviation is determined by finding the z-scores for 3 and 5, and then using a standard normal distribution table. The final calculated probability is rounded to four decimal places.
Step-by-step explanation:
To find
we first need to standardize the values using the z-score formula:
, where
is the value,
is the mean, and
is the standard deviation. Assuming a standard normal distribution, we find the z-scores for 3 and 5.
Next, we use a standard normal distribution table or calculator to find the area between these two z-scores. This area represents the probability
for a standard normal distribution.
The final probability is rounded to four decimal places for precision. This process ensures an accurate representation of the likelihood of the random variable falling between 3 and 5 in a standard normal distribution.
In summary, the solution involves standardizing the values, determining the corresponding z-scores, and then finding the probability in the standard normal distribution table. Rounding the result to four decimal places provides a concise and precise representation of the indicated probability.
