The manufacturers of Good-O use two different types of machines to fill their 25 kg packs of dried dog food. On the basis of random samples of size 15 and 18 from output from machines 1 and 2 respectively, the mean and standard deviation of the weight of the packs of dog food produced were found to be 28.99 kg and 0.142 kg for machine 1 and 26.376 kg and 0.383 kg for machine 2. Hence, under the usual assumptions, determine a 95% confidence interval for the difference between the average weight of the output of machine 1 and machine 2. Use machine 1 minus machine 2, stating the upper limit of the interval correct to three decimal places.

Fill in Table 1 with the resting membrane potentials reported in
different cell types, and different organisms (ie squid, frog, etc)
– Discuss the findings – is the resting membrane potential
different in different tissue types? Is the resting membrane
potential different in the same tissue but from different animals?
Discuss why there are differences and what the likely reason for it
is physiologically.

The company has two machines which are used to fill bottles with
the carbonated beverage. The actual amount filled in each bottle is
assumed to have a normal distribution. For Machine 1, the standard
deviation is known to be s1=0.015 and for Machine 2 it
is known to be s2=0.018. The quality control department
wants to check if the two machines fill the same net volume on
average. They randomly collect 10 bottles which were filled by
Machine 1, and...
