A group of human factor researchers are concerned about reaction to a stimulus by airplane pilots in a certain cockpit arrangement. An experiment was conducted in a simulation laboratory, and 15 pilots were used with an average reaction time of 3.1 seconds with a sample standard deviation of 0.8 second. It is of interest to characterize the extreme (that is, the worst-case scenario). To that end, complete parts (a) through (c) below. Click here to view page 1 of the table of critical values of the t-distribution. Click here to view page 2 of the table of critical values of the t-distribution. Click here to view the table of tolerance factors for normal distributions. Give a particular important one-sided 95% confidence bound on the mean reaction time. What assumption, if any, must you make on the distribution of reaction times? The one-sided 95% confidence interval is u< (Round to three decimal places as needed.) What assumption, if any, needs to be made for the confidence interval in the previous step? O A. The population is normally distributed. O B. The population variance is known. OC. The sample is normally distributed. O D. No assumption is needed.
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.
