I need help with " i. " parts i, ii, iii, iv please it is all the way at the bottom.

3.Following are the published weights (in pounds) of all of the team members of the San Francisco 49ers from a previous year:

177; 205; 210; 210; 232; 205; 185; 185; 178; 210; 206; 212; 184; 174; 185; 242; 188; 212; 215; 247; 241; 223; 220; 260; 245; 259; 278; 270; 280; 295; 275; 285; 290; 272; 273; 280; 285; 286; 200; 215; 185; 230; 250; 241; 190; 260; 250; 302; 265; 290; 276; 228; 265

a.Organize the data from smallest to largest value.

Weight in Lbs

117,174,178,184,185,185,185,185,188,190,200,205,205,206,210,210,210,212,212,215,215,220,223,228,230,232,241,241,242,245,247,250,250,259,260,260,265,265,270,272,273,275,276,278,280,280,285,285,286,290,290,295,302

b.Find the median.

241

c.Find the first quartile.

185

d.Find the third quartile.

259

e.Construct a box plot of the data.

f.The middle 50% of the weights are from _233.92______ to __236.5_____.

g.If our population were all professional football players, would the above data be a sample of weights or the population of weights? Why?

In this instance since this is the weight of all of the San Francisco 49ers this data is representative of the population because it is the total number of people.

h.If our population included every team member who ever played for the San Francisco 49ers, would the above data be a sample of weights or the population of weights? Why?

If we included every player who has ever played and used the data points above this would be a sample because the sample is always less than the population.

i.Assume the population was the San Francisco 49ers. Find:

i.the population mean, .

ii.the population standard deviation, .

iii.the weight that is two standard deviations below the mean.

iv.When Steve Young, quarterback, played football, he weighed 205 pounds. How many standard deviations above or below the mean was he?
