Suppose that P(male birth) = 0.5. A couple wishes to have exactly 2 female children in their family. They will have children until this condition is fulfilled.
a) What is the probability that the family has x male children? (ans: (x + 1) * 0.5^(x+2))
b) What is the probability that the family has four children? (ans: .0.188)
c) What is the probability that the family has at most four children? (ans: 0.688)
d) How many male children would you expect this family to have? How many children would you expect this family to have? (Ans:expected 2 male children , 4 children in total)
How would I go about finding a 95% confidence interval for the population mean if a sample of size 20 has a mean of 18.2 and a sample standard deviation of 3.6?
Standard deviation was $15.50. For 56 Model B ovens, the mean repair cost was $85 and the standard deviation was $30. At alpha=.01, would you buy Model A?
If random sample of 9 loads is selected for weight check, determine probability that mean weight of those loads is more than 40.60 tons.
a psychological test used to measure the level of hostility is known to produce scores which are normally distributed
Create a frequency distribution and histogram for this variable, and calculate the mean, median, and standard deviation. Describe how BankTen compares with other banks in terms of profits per employee.
1. suppose you are calculating an analysis of variance for a completely randomized design. you are testing the
Which of the following would be the hypothesis for testing the claim that the proportion of students at a large university who smoke is significantly different from 0.15?
A previous study of nickels showed that the standard deviation of the weight of nickels is 150 milligrams.
Compute the length-of-life value for which 10% of the watch's batteries last longer.
Conduct a one-tailed hypothesis test given the information below. A certain brand of Green Energy light bulbs was advertised as having an average illumination life-span of 2,500 hours.
Normally distribution with µ=8 minutes and σ=2 minutes. If you select random samples of 25 calls, what percentage of the sample means would be between 7.8 and 8.2 minutes?
If writing scores for population have standard deviation of σ = 20, does sample give adequate evidence to conclude that new composition course has significant effect?
