Module 4 Assignment

 A1. Event A: 30/90= 1/3

A2. Event B: 30/90= 1/3

A3. Event A or B= 5/9

A4. P(A or B)= 2/3

B1. This answer is True

B2. This answer is True because Bayes Theorem states that low base rate of rain makes false positive dominate.

C. 

> dbinom(10,size = 10,prob = .80)

  Question 1: A. The null hypothesis is that the new machine is able to produce cookies with a mean of 70 pounds according to the specification from the manufacture. The alternative hypothesis is that the new machine is not able to produce cookies with a mean of 70 pounds according to the specification from the manufacture. B. To determine if the machine is not meeting the manufacturer's specifications for average strength, I used the test statistic formula to give me the result. The result is -1.8 based on the formula: z = (69.1 - 70) / (3.5 / sqrt(49)) = -1.8 Here is the code in R: C. The equation that I used to compute the p-value was: 2 * (1-pnorm(abs(test_statistic))) The p-value is .07186064 and since the p-value is greater than the alpha value, the null hypothesis is not rejected since there is not enough evidence that the new machine is not meeting the manufacturer's specifications. D. If the standard deviation was 1.75 pounds, then the new z-score is -3.6. This puts th...

   >  assignment2 <- c(6,18,14,22,27,17,22,20,22) >  myMean <- function(assignment2) {return(sum(assignment2)/length(assignment2))} > myMean(assignment2) [1] 18.66667 The function called assignment2 is a numeric vector in R. It contains the given data points for the function myMean to perform its sets of commands.myMean takes one argument, assignment2, and calculate the sum and length of all the elements in the vector. The function returns the result after performing each command. In the end, the result of myMean(assignment2) is 18.66667.

  A. Consider a population consisting of the following values, which represents the number of ice cream purchases during the academic year for each of the five housemates. 8,14,16,10,11 a) Compute the mean of this population I created a vector called ice_cream_purchase from the values that was provided and calculated the mean of the values using the mean() function. The set.seed was to make sure the results of consistent. The mean of this population was calculated to be 11.8. I created a sample of ice_cream_purchase using the sample() function and selected a random sample size of 2. I labeled it as ice.cream.sample. The random sample results were 16 and 14. I computed the mean, sample, and standard deviation of the sample using the mean() and sd() functions. The mean is 15 and the standard deviation is 1.414214 for the sample. I calculated the population mean which is 11.8 as well as the standard deviation of the population which is 3.193744. Next, I compared the sample mean (15) w...
