Part 2: a) Your manufacturing division produces resistors with a nominal value of 22 k0, with a tolerance of +/- 10%. A random sample of ten resistors was taken, and their value was measured by a colleague, to check that they remain within tolerance. The results are as follows: Sample Resistance (Kn) (i) 1 2 22.8 21.7 (0) 3 4 20.5 23.1 5 22.8 6 21.7 7 22.4 8 Two of the eight resistors exceed the tolerance. More than two of the eight resistors exceed the tolerance. 23.2 Calculate the mean resistance for these samples. Determine the standard deviation for the samples. Produce a Tally Chart showing the frequency of measured resistances. 9 21.7 10 b) Further analysis of a larger sample of the resistors shows that 90% are within the allowable tolerance value. The remainder exceed the tolerance. You select eight resistors at random from the sample. Determine the probabilities that: 22.8

Radon is a gas emitted from the ground that can collect in houses in buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered “acceptable” Radon levels in a house vary from week to week. In one house, a sample of 6 weeks had the following readings for radon level (in pCi/L): 1.9 2.8 3.9 3.9 4.2 5.7 Find the variance and standard deviation (definitional formula). Show your work using a table.
