Using the number 5, 10, 15, 20, 25, and 30 as the element of the population, construct the sampling distribution of the sample means with a sample size of 2. Find the population and sample mean, population and sample variance, and population and sample standard deviation.
According to NSC statistics,the life expectancy of Filipino women is 70.1 years. Suppose a random sample of 30 women in town B yields a mean of 72.5 years with a population variance of 4.76 years, would you say that the life expextancy of the women in town B is greater than the average?Formulate the null and alternative hypothesis and in symbol.

Do the following by using Recursion:
1. Create a code that can print any numbers depending on the inputted value of the user in ascending then reverse it in descending order.
Sample output:
Enter number: 5
1
2
3
4
5
4
3
2
1
2. Write a code that will identify if the inputted value is odd or even. If it is odd then get the sum of all the odd numbers prior to the inputted value, same goes if it is even then get the sum of all the even numbers.
Sample output:
Enter number: 9
Odd
The sum is: 25
3. Using the fibonacci sequence, create a code that will print the remainder using %5 of the sum of the 2 added value depending on the input term of the user.
Sample output:
Enter 1st term: 5
Enter 2nd term: 6
The sum is: 13
The remainder is: 3
A classroom teacher hypothesizes that using lecture method in teaching specific lesson is the same as teaching it using demonstration method in terms of students learning. This means that students who were taught using the lecture method would perform similary(say on test)than those were taught using demonstration method. Formulate the null and alternative hypothesis in sentence and in symbol.
