X flight timess of all paper airplanes created by our lab X

X = flight times(s) of all paper airplanes created by our lab

X = ( 0.94, 2.4, 1.08, 2.46, 1.2,1.73, 2.00, 2.06, 1.35, 1.15, 1.84, 1.49, 3.75, 0.95, 0.73, 1.55, 2.11, 1.69, 1.90, 1.23, 3.28, 2.99, 1.63, 2.35, 2.73 )

1) Use R to generate 100 samples of size 10 from the distribution of X. You will need to use the replace = TRUE subcommand. For each sample, calculate the mean. These 100 sample means constitute a sample of size 100 from the distribution X . R commands you used to generate it.

2) Draw a histogram of the sample from X chosen above and find the mean and standard deviation of the sample.
