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.

According to a report published by the USDA 4 years ago, a typical American consumes an average of 6.66 pounds of potato chips per year.A researcher at the USDA would like to determine if the average amount of potato chips consumed each year by a typical American has changed since the original report was published. The researcher collected data from a random sample of 31 Americans and found that the mean amount of potato chips consumed each year by the sample was 6.37 pounds with a standard deviation of 0.603 pounds.Using α=0.05α=0.05, test the hypothesis that the mean amount of potato chips consumed each year by a typical American is different than 6.66 pounds. Use the p-value method. Determine the test statistic for the hypothesis test.

Suppose you run a non-for-profit organization focused to keeping national parks free of litter. Crucial to getting donations to your non-for-profit is email advertising. One way to measure the success of your email advertising is to measure the amount of money coming from links to donate on your emails. Normally, your emails contain only words and numbers about litter in national parks. You believe that including images of littered areas of national parks might increase the amount in donations that you get through emails. To test if this is true, you randomly assign 50 individuals to receive the new email format with images and 42 to receive your usual email format (this is called an A/B test). The new email format had an average donation per recipient of$5.50 with a standard deviation of$2.75 while the old email format had an average donation per recipient of$3.50 with a standard deviation of$2.50. Does the average donation differ between the new and old email formats? Letμ1be the…
Researchers conducted a study on using a chief executive officer's facial structure to predict a firm's financial performance. The facial width-to-height ratio (WHR) for each in a sample of 53 CEOs at publicly traded firms was determined. The sample resulted in x= 1.94 and s = 0.15. An analyst wants to predict the financial performance of a firm based on the value of the true mean facial WHR of CEOs. The analyst wants to use the value of u = 2.2. Do you recommend he use this value? Conduct a test of hypothesis for u to help you answer the question. Specify all the elements of the test, including Ho, Ha, test statistic, p-value, and your conclusion. Test at a = 0.05.

Before going to college, Chelsea wanted to see if she could sell her old car online. She selected a sample of the prices on 25 similar cars sold online in the past month. Later, Chelsea realized that the lowest-priced car in the sample was mistakenly recorded as half the price it actually sold for. However, after correcting the error, the corrected price was still less than or equal to any other car price in her sample. Which of the following sample statistics must have remained the same after the correction was made? Select one: 1.Range 2.Median 3.Mode 4.Variance 5.Mean
The blue catfish (Ictalurus Furcatus) is the largest species of North Amercian catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to Amercian Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds.a) If you going to test this claim at the 0.05 significance level, what would be your null and alternative hypotheses?H0H0: H1H1: b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed
In a 2015 study entitled How Undergraduate Students Use Credit Cards, it was reported that undergraduate students have a mean credit card balance higher than $3000. This figure was an all-time high and had increased 42% over the previous five years. Assume that a current study is being conducted to determine if it can be concluded that the mean credit card balance for undergraduate students has continued to increase compared to the report. They want to test to see if the balance for students in 2019 is higher than the balance for students in 2015. See the sample below of undergraduate students in 2015 and different undergraduate students in 2019.
