The weight of 30 rаndomly and independently selected bags of potatoes labeled 2 pounds in a store were measured. Mean weight of this sample was 2.1 pounds and standard deviation was 0.2 pounds. Using the formula and the multiplier (t*) from the below t-distribution table, find the 95% confidence interval of the mean weight of bags of potatoes labeled 2 pounds in the store. Assume all conditions are met. Show your work.

A scientist designed аn experiment tо аssess grоwth in kоi by setting up three ponds. Eаch pond had identical volumes of water with the same salinity and ph, access to light and identical brands of fish food. The recommended food requirement for koi in captivity is 30 mg twice per day. Koi in pond A were given 15 mg twice per day, pond B koi were given 30 mg twice per day and koi in pond C were given 45 mg twice per day. A research assistant fed fish in all ponds at the same time each day and once per week would observe and record color changes in koi in each tank using a descriptive color chart and would measure and weigh all koi using a tape measure and scale.
