An article in the San Jose Mercury News stated that students in the California state university system take 4.5 years, on average, to finish their undergraduate degrees. Suppose you believe that the mean time is longer. You conduct a survey of 48 students and obtain a sample mean of 5.1 with a sample standard deviation of 1.2. Do the data support your claim at the 1% levei? Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) O Part (a) O Part (b) O Part (c) O Part (d) State the distribution to use for the test. (Enter your answer in the form z or tar where df is the degrees of freedom.) O Part (e) What is the test statistic? (If using the z distribution round your answers to two decimal places, and if using thet distribution round your answers to three decimal places.) -Select-- v = O Part (f) What is the p-value? (Round your answer to four decimal places.) Explain what the p-value means for this problem. O If H, is false, then there is a chance equal to the p-value that the average time needed to complete an undergraduate degree is 5.1 years or more. O If Ho is true, then there is a chance equal to the p-value the average time needed to complete an undergraduate degree is not 5.1 years or more. O If Ho is false, then there is a chance equal to the p-value the average time needed to complete an undergraduate degree is not 5.1 years or more. O If Ho is true, then there is a chance equal to the p-value that the average time needed to complete an undergraduate degree is 5.1 years or more.

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.
