Programming Assignment #2 (Arrays) I. The Assignment This assignment is to take your Garage class from the previous assignment and modify it so that it uses an array of Car objects as the principal data structure instead of an ArrayList-of-Car. This is an example of the OOP principle of information hiding as your Car and test classes will not have to be modified at all. Unless you broke encapsulationon the previous assignment, that is II.

1. Suppose you are going to conduct a two tail test concerning the population mean. Suppose that you do not know what the population standard deviation is and that you have a sample of 55 observations. If you are going to conduct this test at the .01 level of significance what is the critical value? Be sure to enter a positive number and answer to four decimal places. 2.The p-value is? Group of answer choices: the probability of a Type...
4. Suppose you take a one hour car ride, and this is the graph of your velocity as a function of time during the trip. velocity (miles per hour) Po 10 50 60 20 30 40 time (minutes) (a) What is your velocity (in miles per hour) at the 50 minute mark of your trip? (b) What is the total distance (in miles) that you travel during the trip? (c) Did you travel further during the first 30 minutes or...
anufacturer claims that your new car gets 32 mpg on the highway. You suspect that the mpg is a different number for your car. The 52 trips on the highway that you took averaged 26.9 mpg and the standard deviation for these 52 trips was 12.6 mpg. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: HO: ? Select...

The manufacturer claims that your new car gets 25 mpg on the highway. You suspect that the mpg is a different number for your car. The 57 trips on the highway that you took averaged 23.3 mpg and the standard deviation for these 57 trips was 4.3 mpg. What can be concluded at the αα = 0.10 level of significance? For this study, we should use: t-test for a population mean or z-test for a population proportion The null and...

You have been hired to test whether the demand for a product that your client produces varies between two demographic markets – the Urban and Rural markets. As such, in each market, you run a short survey that gauges customers demand for your product and assigns them to one of three categories – (i) High (ii) Medium or (iii) Low. You survey 70 people in the “Urban” market and find that their demand falls into the following “buckets” High 32...
