Answer and step-by-step explanation:

Making all of the stripes the same with means that we divide 15 yards by the 96 stripes:

15/96 = 0.15625 yards per stripe

There are 3 feet in every yard; this means that each stripe would be

0.15625(3) = 0.46875 foot

There are 12 inches in every foot; this means that each stripe would be

0.46875(12) = 5.625 inches

This is 5 5/8 inches per stripe.

Answer:

see below

Step-by-step explanation:

a)  median : re-arranged the numbers in order. i.e. min to max

gold:          147 , 147 , 175 , 206 , 212 , 227 , 263 , 275 , 440 , 1022

                 <u>212  + 227</u><u>  </u>  =  219.50

                        2

silver:       147 , 163 , 165 , 170 , 178 , 241 , 295 , 313 , 357 , 794

                <u>178 + 241  </u>   =  209.50

                       2

bronze:    151 , 169 , 179 , 187 , 193 , 260 , 289 , 325 , 349 , 704

                <u>193  +  260  </u>=  226.50

                        2

b)  mean : sum of all numbers divide by n, where n=10  

gold:        =   (147 , 147 , 175 , 206 , 212 , 227 , 263 , 275 , 440 , 1022 ) / 10

               =  311.40

silver:      =   (147 , 163 , 165 , 170 , 178 , 241 , 295 , 313 , 357 , 794 ) / 10

              =  282.30

bronze:   =  (151 , 169 , 179 , 187 , 193 , 260 , 289 , 325 , 349 , 704 ) / 10

               =  280.60

c) standard deviation on population (STDEV.P)

Australia          = 16.44

china               = 33.03

france              = 19.74

germany          = 30.21

great britain    = 13.89

hungary           = 12.04

italy                  = 11.44

soviet union    = 48.46

sweden           = 13.47
