Acrylic bone cement is commonly used in total joint replacement to secure the artificial joint. Data on the force (measured in Newtons, N) required to break a cement bond was determined under two different temperature conditions and in two different mediums appear in the following table.
| Temperature | Medium | Data on Breaking Force |
| 22 degrees | Dry | 100.7, 142.7, 194.8, 118.4, 176.1, 213.1 |
| 37 degrees | Dry | 302.2, 338.3, 288.8, 306.8, 305.2, 327.5 |
| 22 degrees | Wet | 385.4, 367.2, 322.6, 307.4, 357.9, 321.4 |
| 37 degrees | Wet | 363.8, 376.6, 327.7, 331.9, 338.1, 394.6 |
(a) Estimate the difference between the mean breaking force in a
dry medium at 37 degrees and the mean breaking force at the same
temperature in a wet medium using a 90% confidence interval. (Round
your answers to one decimal place.)

Acrylic bone cement is sometimes used in hip and knee
replacements to secure an artificial joint in place. The force
required to break an acrylic bone cement bond was measured for
eight specimens, and the resulting mean and standard deviation were
306.01 newtons and 41.92 newtons, respectively. Assuming that it is
reasonable to believe that breaking force has a distribution that
is approximately normal, use a 95% confidence interval to estimate
the mean breaking force for acrylic bone cement. (Use...

Ethyl butyrate, CH3CH2CH2CO2CH2CH3, is an artificial
fruit flavor commonly used in the food industry for such flavors as
orange and pineapple. Its fragrance and taste are often associated
with fresh orange juice, and thus it is most commonly used as
orange flavoring.
It can be produced by the reaction of butanoic acid
with ethanol in the presence of an acid catalyst
(H+):
CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l)
Part A)
Given 7.50 g of butanoic acid and excess ethanol, how many grams
of ethyl butyrate...
