I need Answer for Exercise ( 1 - 8 ), ( 1 - 9 ), ( 1 - 10 ) and ( 1 - 11 )

220AL-E1 function to calculate eqs 1-1 and 1-2. It is well worth while to take the time to learn to use that function. Notice also the factor n - 1 in the denominator: there are functions on some calculators that compute eq 1-2 using a factor of n rather than n - 1; thus you need to check. Test your calculator's result against the long-hand calculation of exercise 1-7. since we may combine all those of the same diameter.

Explanation / Answer

using the equations

the mean = 4.44

standard dev = 1.79
