For a hypothesis test of the claim that the mean amount of sleep for adults is less than 8 hours, technology output shows that the hypothesis test has power of 0.4166 of supporting the claim that u<8 hours of sleep when the actual population mean is 7.0 hours of sleep. Interpret this value of the power, then identify the value of ß and interpret that value. Interpret this value of the power. O A. The chance of failing to recognize that u =7.0 hours is not very high when in reality u =7.0 hours. O B. The chance of failing to recognize that p <8 hours is not very high when in reality u =7.0 hours. OC. The chance of recognizing that u<8 hours is very high when in reality u =7.0 hours. O D. The chance of recognizing that u<8 hours is not very high when in reality u = 7.0 hours. Identify the value of B and interpret that value. Select the correct choice below and fill in the answer box to complete your choice. (Round to four decimal places as needed.) O A. The value B= indicates that there is a less than 50% chance of failing to recognize that u<8 hours when in reality u=7.0 hours. O B. The value B= indicates that there is a greater than 50% chance of failing to recognize that u<8 hours when in reality u=7.0 hours. O C. The value B= indicates that there is a less than 50% chance of incorrectly recognizing that u<8 hours when in reality u =8 hours. O D. The value B= indicates that there is a greater than 50% chance of incorrectly recognizing that u<8 hours when in reality u = 8 hours.

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.
