The article “Arsenic and Mercury in Lake Whitefish and Burbot Near the Abandoned Giant Mine on Great SlaveLake” presents measurements of arsenic concentrations in fish found in Northern Canada.
a. In a sample of 8 whitefish caught in Yellowknife Bay, the mean arsenic concentration in the liver was 0.32 mg/kg, with a standard deviation of 0.05 mg/kg. Find a 95% confidence interval for the concentration in whitefish found in Yellowknife Bay. b. In a sample of 8 whitefish caught in Baker Pond, the mean arsenic concentration in the liver was 0.55 mg/kg, with a standard deviation of 0.36 mg/kg. Should the Student’s t distribution be used to find a 95% confidence interval for the concentration in whitefish found in Baker Pond? If so, find the confidence interval. If not, explain why not.

For the circuit in Figure P5.47, assume
VS = 100V, RS = 4k?, R1 = 2k?, R2 = R3 = 6k?, C = 1?F,
and the circuit is in a steady-state condition before the switch opens. Find the value of vC 2.666 ms after the switch opens.
