QUEStIOH 9 2 points Save Answer PintPant, a paint company, is looking to ensure that every customer gets a fair amount of paint when they buy PintPant's products. PintPant decided to test 150 cans they produced on the day as a sample for the day's manufacturing and found that the average amount of paint in each tin was 3.99 litres with a standard deviation of 0.2934 litres. Determine the number of observations needed to be 93% confident that the estimate of the average weight is within 0.03 litres of the overall mean volume. Note: Assume that the standard deviation is a good estimate of the population standard deviation, that an appropriate value from the Z-table can be used, and that hand calculations are used to find the answer (i.e. do not use Kaddstat)
