Create a PHP class named "User" with the following private fields:

name,

birthdate in yyyy/mm/dd format,

age, and

department.

In the class, include getter and setter methods to get and set the values of those variables.

Author a data entry webform using HTML text input boxes and a submit button. When the user clicks on the submit button, a "User" class is instantiated and the new User object's fields are populated. The HTML input boxes correspond to the field in the "User" class.

Add an "Insert" button that allows the user to insert the form data to a MySQL table.

Add a "Display" button the displays the contents of your MySQL table on the web form when the end-user clicks on the button.

Nina is looking to analyze the distribution of the variable X=’grading. She gathered information from 1900 to 2000, and her data concludes X follows a normal distribution with mean 75 and variance 30.

1. What is the probability that a typical student from the current cohort enrolled receive a grade above 80?
2. Between what values will the grades of the 95% of all students in the current cohort fall?
3. Find the value that represents the 25^th and 75^th percentile of this distribution. Then, find the interquartile range. Can a student who got 45 be considered a potential outlier, explain the reasoning.

PLEASE SHOW EACH STEP AND EXPLAIN EACH STEP AS TO WHERE YOU ARE GETTING VALUES FROM (i.e., if you got value from z table, tell me why you use that table and where exactly). use mathematical formula as well as give me a reason why you used what formula you used.

The Cambridge Study of delinquent development was undertaken in N. London to investigate the links between criminal behavior in young men and socioeconomic factors of the upbringing. A cohort of 395 boys was followed for about 20 years starting at the age of 8 or 9. All boys attended 6 schools located near the research office.

The table below provides the following summary statistics relating family income and convictions.

Income level

• Can we consider the cohort of these boys to be a random sample of a certain portion of the male youth of UK?
• What is the necessary assumption that needs to be made about the income group assignment of these boys for the duration of the study?
• Identify the random variables of the data set. What is the type of these variables?
• Construct the appropriate plot of these data.
• Do the two random variables seem to have an association? Which one can be used as explanatory?
