Use the following excerpt to answer the questions below. In the state of California, there is an average 7,500 individuals enrolled in Medicare Insurance per 10,000 eligible individuals with a known standard deviation of 1,000 enrollees per 10,000 eligible. This average was calculated from insurance data collected from all cities in California and appears to be normally distributed. You are interested in whether the average number of those enrolled in Medicare per 10,000 eligible in the Bay Area is greater than the state of California's average; they find that = 7,800 Medicare enrollees from a random sample of 100 eligible Bay Area individuals. State the null and alternative hypothesis using statistical notation. a. Ho: HA: b. Use the information above to decidethe appropriate test statistic and calculate the test statistic value by hand. Show your work. Test Statistic: Work: Value: Next, you want to calculate the power of the test. Write the two lines of code to calculate the power assuming alpha 0.05, assigning the first value to an object called critical val. C. Line 1: Line 2:
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.
