Solution: From the given information, n=25,

A lot of people have difficulty in getting good sleep of more than 7 hours per day. An investigator is trying to find if exercise of one hour or more per day helps, and wants to test the hypothesis: Но : µ = 7 versus Ha : µ > 7

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

A group of researchers is asked to check whether the average weight of penguins in a certain colony has changed since last year. Last year, the average weight was 5.5 pounds. This year, they find an average weight of 5.3 pounds. If it is later discovered that the researchers made a type II error, what happened? The researchers decided that the average weight of the penguins did change, but it later turned out that it did not. The researchers decided that the average weight of the penguins did not change, but it later turned out that it did. The researchers were not able to arrive at a conclusion and had to repeat their work with a larger sample size.

The number of Muslims continues to grow throughout the world, and they are currently thesecond-largest religious group in the world. Knowing that this group has been the target of falsebeliefs about their religion, a researcher is interested in whether people who have moreinteractions with Muslim people are less likely to believe negative statements about Islam. To dothis, they surveyed a large sample of participants across Western Europe and asked themquestions about how frequently they interact with Muslim people as well as how much theyagreed with negative statements about Islam. What statistical test should be used to determine ifthere if how frequently survey participants interact with Muslim people predicts how likely theyare to agree with a negative statement about Islam?
