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

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
united states = 133.84
