For questions 1 and 2 use the following info. The numbers are in this order: 456,306,160,363,376,935,54,349
1)Find the mean, median ,mode, and standard deviation of the data. Round to the nearest hundredth, if nessesary.
mean= added all numbers and divided by 8 and got 384.9
median= subtracted largest number and smallest number and got 881
mode= clustered values such as 306,363,376,349 so the mode is 300
standard deviation= I had to find the variance first which is 59476.6 and I took the sqrt of that and got 243.9
2)Determine whether the data in the table appears to be positively skewed, negatively skewed, or normally distributed. Explain.
Normally distributed but I can't explain.
say that you were looking at your already completed work and found that it was normally distributed.
