  1. You want to understand sampling distribution. The average number of children per woman is 2.2 with a standard deviation is .1. If you took a sample of 16 women, what is the probability that:
    1. The average of this group is less that 2.3?
    2. The average for this group is greater than 2.45?
    3. The average for this group lies between 2.15 and 2.4.                                                      (10)

You are not sure if the mean value is correct but you believe that the standard deviation is correct. You took a sample of 16 women and average number of children for this group is 2.4. Prepare a confidence Interval for the mean number of children for a woman.

The mean number of shopping trips per week in a county is 2.2. In a particular neighborhood within the county, a survey based on 50 people reveals that the mean in the neighborhood is 1.85, with a standard deviation of 1.2. Test the null hypothesis that the mean in the neighborhood is no different from that in the county. State the null and alternative hypotheses, find the test statistic, compare it with the critical value, make a decision, and find...

The number of accidents per week at a hazardous intersection varies with mean 2.2 and standard deviation 1.4. The distribution takes only whole-number values, so it is certainly not normal. A) Let x-bar be the mean number of accidents at the intersection during a year (52 weeks). What is the approximate probability that x-bar is less than 2? B) what is the approximate probability that there are fewer than 100 accidents at the intersection in a year? Hint: re-state the...
