Please answer the following questions which are based on the dataset (Cars). You can only use Stata class materials or online sources. 1. What percent of sampled cars were foreign in 1978?
a. Syntax:
2. What is the mean weight of cars in 1978?
a. Syntax:
3. Compute the average prices for mpg greater than 20
a. Syntax:
4. Create a histogram for the variable mpg.
a. Syntax:
5. What are the four most expensive cars in 1978?
a. sort Syntax:
b. list Syntax:
6. Perform a regression to determine if a car’s mpg helps determine its price.
Produce an appropriate scatter plot.
a. regress Syntax:
b. scatter Syntax:
7. What happens if we add weight as an independent variable to our analysis?
a. Syntax:
8. Create a new variable efficiency that groups different levels of mpg efficiency. Assume the following: a car that gets less than 15 mpg is “inefficient”, between 15 and 30 mpg is “moderately efficient”, and above 30 mpg is “efficient”.
How many are considered “efficient”?
a. recode, gen() Syntax:
b. label variable Syntax:
c. tabulate Syntax:

just need Syntax not in prgram
just the code by STATA language

Well, this code would box the whole body of an html document. by using the relative value for position, you are telling it to position relative to its normal position, which the top left corner is at (0,0). by using left: 50px, you are telling the box to set the left margin  edge to 50px and by using top: 50px, you are telling it to set the top margin edge to 50px. by doing this shifting, the top left corner of the box, which is at (0,0) would be positioned at (50,50)

(1)correct answer is d.the others are just bad syntax.by using the keyword "new" and int[] together, you create a new integer array object in memory. whenever you want to create an object without using array literals, you must use new. (by array literals, i mean a line of declaration code like int[] x = {4,6}; where you literally specify an array without using new. an array literal can only be used in the same line as declaring the array.)(2)correct answer is c. it is the only choice that returns an array and properly takes in an array reference as an argument.choices a and b do not return an array; they respectively return void (nothing at all) and a primitive double, which is not a double array.choice d has invalid syntax. looking at it, it won't properly accept any array reference you pass into the method.(3)correct answer is a.x is already defined.choice b only returns an index of the array.also, in any other method, you wouldn't write the type next to the thing being returned. choices c and d are invalid.(4)correct answer is c.choice a only accepts one.choice b requires at least two numbers.choice d only takes in an integer array reference, not integers.(5) correct choice is d.by specifying that the first argument can take in any number of ints, java will assume everything you input into the method will be an integer.theoretically it will never reach that string argument, no matter how many commas you put. this is illegal; the java compiler will complain. i don't think it'll even recognize it as a method header.
