Program Plan Intro

Modified statistics program

Program plan:

Import the necessary modules.

Define the “mean()” function,

Returns mean value to the caller.

Define the “StdDev()” function,

Returns standard deviation value to the caller.

Define the “meanStdDev()” function,

Returns average standard deviation value to the caller.

Define the “median()” function,

Returns median value to the caller.

Define the “main()” function,

Get comma separated values from the user.

Separate the value based on “,” using “split()”.

Create a “for” loop to iterate over comma separated values.

Assign the value.

Print the options.

Create sentinel loop to get numbers.

Prompts the user for the type of operation to perform.

Check whether the operation is “Avg” using “if” .

If it is true, print mean value return from “mean()” function.

Otherwise, check whether the operation is “Med” using “elif”.

If it is true, print median value return from “median()” function.

Otherwise, check whether the operation is “Std” using “elif”.

If it is true, print standard deviation return from “stdDev()” function.

Otherwise, check whether the operation is “AvgStd” using “elif”.

If it is true, print average standard deviation value return from “meanStdDev()” function.

Otherwise, check whether the operation is empty (‘ ‘)using “elif”.

If it is true, use “break” to exit.

Otherwise print “Please try again”.

Call the “main()” function.

Can you help me solve this problem using Master's Theorem:Solve the recurrence relation f(n) = 3af(n/a) + (n + a)2 with f(1) = 1 and a > 1 byfinding an expression for f(n) in big-Oh notation.

here is example 7.6## Example 7.6 Suppose the sample population is χ 2 (2), which is non-normal but with same variance 4. ▶ Repeat the simulation, but replacing the N(0, 4) samples with χ 2 (2) samples. ▶ Calculate the empirical confidence level.(Empirical confidence level) n <- 20 alpha <- 0.05 UCL <- replicate(1000, expr = { x <- rchisq(n,df=2) (n-1)*var(x)/qchisq(alpha,df=n-1) }) sum(UCL >4) mean(UCL > 4) ## t.test function n <- 20 x <- rnorm(n,mean=2) result <- t.test(x,mu=1) result$statistic result$parameter result$p.value result$conf.int result$estimate
