Explanation of Solution
Given:
Different types of writing can sometimes be distinguished by the lengths of the words used. A student interested in this fact wants to study the lengths of words used by J. K. Rowling in her Harry Potter books. She opens a Harry Potter book at random and records the lengths of the first 50 words on the page.
First need to understand about sample and population.
Population: It is the set of all the possible individuals possessing the characteristic of interest in a study.
Sample: It is the subset of population on which, the actual study performed and from which, the necessary measurements are taken.
In given study,
Population: The different types of writing from all books.
Sample: The lengths of the first 50 words on the page from Harry Potter book.

- A company found that the daily sales revenue of its flagship product follows a normal distribution with a mean of $4500 and a standard deviation of $450. The company defines a "high-sales day" that is, any day with sales exceeding $4800. please provide a step by step on how to get the answers in excel Q: What percentage of days can the company expect to have "high-sales days" or sales greater than $4800? Q: What is the sales revenue threshold for the bottom 10% of days? (please note that 10% refers to the probability/area under bell curve towards the lower tail of bell curve) Provide answers in the yellow cellsarrow_forwardFind the critical value for a left-tailed test using the F distribution with a 0.025, degrees of freedom in the numerator=12, and degrees of freedom in the denominator = 50.
