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.

17. Dieticians claim that most adults do not intake enough dietary fiber from food (not supplements).
For optimal health, adults should intake an average of twenty-eight grams of fiber from food per
day. Below is the amount of dietary fiber from food consumed by twenty randomly selected adults.
At the 5% significance level, can we conclude that the average amount of dietary fiber from food
consumed per day is less than twenty-eight grams?
