6. An experiment has been designed for an effective remedy for athlete's foot. A researcher claims that this new treatment will cure 75% of athlete's foot within a week. This claim has been challenged as too high. To disprove the claim of 75%, the experiment treats 30 people with this new remedy. Suppose we wish to test Ho : p= 0.75 versus Ha :p < 0.75 with a rejection region of Y < 19 where Y is the number of people whose athlete's foot is cured within a week. (a) In words explain, What is a Type I error in this problem? (b) Find a for this test. (c) In words explain, what is a Type II error in this problem?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
