Hello, can a get a paragraph given another example like (or contradicting) the following and an explanation of how it can be use in business.
"One of the hypothesis you can give for a test is the null hypothesis. This theory is looked at as the status quo; you can assume that whatever you are researching has no effect. The other is the alternative hypothesis. This theory is the one in which we say that our test will have an effect or result.
For example; we are testing out a drug on a group of individuals and we are injecting 100 people with a dose of this drug. We know that the mean response time for people not injected with any drug is 1.2 seconds and the mean of the 100-injected individual's response time is 1.05 seconds with a standard deviation of 0.5 seconds. One of our hypothesis (the null) is saying that the drug is not going to have any effect on our individuals; it's not going to work. Our second hypothesis (the alternative) is the assumption that our drug will have some effect on the test panel of people".
Hey! Could anyone help me with this question? It would be much appreciated, thank you!
Find the values of 'x' for which the function f(x)=2x+3+ (18/x-4) is increasing.
A bag contains 3 black counters, 4 red counters and 5 blue counters. A counter is taken at random down the probability that it is a black or red counter.
Basic lists Make a program that lets a user input a series of names into a list. The program should then ask the user whether they want to print out the list in the original order, or in reverse. Extensions: 1. Enable the user to choose what number item in the list they want to print out 2. Enable the user to only print out a ‘slice’ of the list (eg item three to item nine only) 3. Enable the user to remove any items of the list that they want to 4. Enable the user to save their list to a file for later, and also enable them to load it back up again too 5. ‘Clean’ the list by making all the items lowercase.
Averages Make a program that asks the user for a series of numbers until they either want to output the average or quit the program. Extensions: 1. Expand the program to print the median and mode averages also 2. Include options so that if the user wants to, they can save their list of numbers to a text file and read them back out later on.
