Your work with the wire spools leads you to believe that the previously recorded standard deviation of 10 pounds of failure tensile strength in the wire is too high. You ask the quality engineer to run a test of incoming wire failure tensile strengths and he reports that in a sample of 20 spools, he has a sample standard deviation of 9.5 pounds. Run a hypothesis test with a significance level of 0.05 to see if the standard deviation has decreased from 10 pounds. Again, record the null and alternative hypotheses on the Excel sheet and write 'sigma' for o and write 'sigma^2' for o? in your hypotheses.
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
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
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.
