4.17 During the assembly of an exhaust valve, sufficient dis- tance must be maintained between the valve tip and the cylinder wall. If 85% of valve assemblies have the required distance, use Table 1 or software to find the probabilities that among 20 such valves: (a) at least 15 will have the required distance; (b) at most 10 will have the required distance; (c) exactly 18 will have the required distance.

Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is designed to increase the likelihood that each baby will be a girl, but assume that the method has no effect, so the probability of a girl is 0.5. Assume that the groups consist of 23 couples. Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of girls in groups of 23 births. The value of the mean is µ = (Type an integer or a decimal. Do not round.) The value of the standard deviation is o = (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high. Values of girls or fewer are significantly low.
