Descriptive Statistics


In this week assignment i was task to compute the mean, mode, median, range, interquartile, variance, standard deviation for two set data with sample size of n=7.  from what observes the Y data have higher mean and median than the X data. the mode for both X and Y are numeric which mean both data doesn't have a mode because of the sample size. the variance of both data are the same occurrences of deviation. the quantile for Y data is much higher than X data. below is my code for the X and Y data. 


R Code 
#two sets of data
 x <- c(10, 2, 3, 2, 4, 2, 5)
y <- c(20, 12, 13, 12, 14, 12, 15)

#calculate the mean for x and y
mean(x)
  [1] 4
mean(y)
  [1] 14

#calculate the mode for x and y
mode(x)
  [1] "numeric"
mode(y)
  [1] "numeric"

#calculate the median for x and y

 median(x)
  [1] 3
 median(y)
  [1] 13

#calculate the variance for x and y
var (x)
  [1] 8.333333
var(y)
  [1] 8.333333

#calculate the standard deviation  for x and y
sd (x)
  [1] 2.886751
sd(y)
  [1] 2.886751

#calculate the quantile for x and y

quantile(x)
  0%  25%  50%  75% 100%
  2.0  2.0  3.0  4.5 10.0

quantile(y)
  0%  25%  50%  75% 100%
  12.0 12.0 13.0 14.5 20.0

  #calculate the range for x and y
  range(x)
  [1]  2 10

   range(y)
  [1] 12 20

#print out the summary(x) and summary(y)

 summary(x)
  Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
  2.0     2.0     3.0     4.0     4.5    10.0

 summary(y)
  Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
  12.0    12.0    13.0    14.0    14.5    20.0

Confidence Interval Estimation And introduction to Fundamental of hypothesis testing

1. x̄ = 85 and σ = 8, and n = 64, set up a 95% confidence interval estimate of the population mean μ.  Z= 1-(0.05/2) = 1.96 Sample mean= x-bar = 85 Z*s/sqrt(n) = (1.96*8)/sqrt(64) = 1.96 CI= 85 – 1.96= 83.04 CI= 85- 1.96= 86.96 (83.04, 86.96) 2. If  x̄ = 125, σ = 24 and n = 36, set up a 99% confidence interval estimate of the population mean μ.  Z= 1- (0.01/2) = 0.995= 2.57 Z*s/sqrt(n) = 125 - (2.57*8/sqrt(36) = 3.42-125= 121.58 Z*s/sqrt(n) = 125 + (2.57*8/sqrt(36) = 3.42+125= 128.42 3. The manager of a supply store wants to estimate the actual amount of paint contained in 1-gallon cans purchased from a nationally known manufacturer. It is known from the manufacturer's specification sheet that standard deviation of the amount of paint is equal to 0.02 gallon. A Random sample of 50 cans is selected and the sample mean amount of paint per 1 gallon is 0.99 gallon.  3a. Set up a 99% confidence inter...

Hypothesis Testing and Correlation Analysis

The director of manufacturing at a cookies needs to determine whether a new machine is production a particular type of cookies according to the manufacturer's specifications, which indicate that cookies should have a mean of 70 and standard deviation of 3.5 pounds. A sample pf 49 of cookies reveals a sample mean breaking strength of 69.1 pounds. A.  State the null and alternative hypothesis   Ho = u>=  70  and alt hypo. Ho = u<70 B.  Is there evidence that the machine is nor meeting the manufacturer's specifications for average strength? Use a 0.05 level of significance .  since the data is random sample size the data seem almost approximate normal.  C.  Compute the p value and interpret its meaning?  (xbar - mu) / (stdsqrt(n)) = (69.1 - 70)/(3.5/sqrt(49)) =  -1.80 this indicted it does not fall under the region and it is rejected.  D.   What would be your answer in (B) if the standard deviation were specified...
