Question

During the winter months, the temperatures at the Starneses' Colorado cabin can stay well below freezing 32°F or 0°C) for
weeks at a time. To prevent the pipes from freezing, Mrs. Starnes sets the thermostat at 50°F. The manufacturer claims
that the thermostat allows variation in home temperature of o = 3°F Mrs. Starnes suspects that the manufacturer is
overstating the consistency of the thermostat.
What are the appropriate hypotheses for performing this significance test?
Ho: o = 3, H, o 3, where o = the true standard deviation of the temperature in the cabin.
Ho : o = 3, H, o> 3, where o = the true standard deviation of the temperature in the cabin.
Ha: o < 3;H, o>3, where o = the true standard deviation of the temperature in the cabin.
Ho: o = 3; H,: o<3, where o = the true standard deviation of the temperature in the cabin
He: o < 3,H,: o2 3, where o = the true standard deviation of the temperature in the cabin.

In Hawaii, electricity is very expensive (the most expensive rate in the United States). The electricity rate there is 33.0 cents per kWh (kilo-Watt-hour). How much would it cost for you to cook a large 25.0-pound turkey for Thanksgiving if your turkey roaster operates at 1800.0 Watts at 325.0°F (you are following your Aunt's trusted advice and cooking it for 15.0 minutes per pound at 325.0°F)?

When a forensic expert determines time of death, they often have additional information besides body temperature. Suppose a coroner finds that the person who was murdered had an infection that probably raised the core body temperature to around 102 degrees. Using the same cooling constant, ambient room temperature, and temperature data as in problem 1, make a new estimate for the time of death. Again, write your answer as a time, not just as ? minutes.

The object of a general chemistry experiment is to determine the amount (in millilitres [mL]) of sodium hydroxide (NaOH) solution needed to neutralize 1 g of a specified acid. This will be an exact amount, but when the experiment is run in the laboratory, variation will occur as the result of experimental error. Three titrations are made using phenolphthalein as an indicator of the neutrality of the solution (pH equals 7 for a neutral solution). The three volumes of NaOH required to attain a pH of 7 in each of the three titrations are as follows: 82.20, 75.80, and 75.34 mL. Use a 99% confidence interval to estimate the mean number of millilitres required to neutralize 1 g of the acid. (Round your answers to three decimal places.) mL to
