Three bombers are attempting to hit a target deep behind enemy lines. The bombers success rates for bomber A, B and C are: 30%, 45% and 60% respectively. Find the probability that:
A) Bomber A will succeed, but bomber B and C will fail.B) Bomber B and C succeed, but bomber A fails.C) All three bombers fail.D) At least one of the bomber succeeds.
Bowling balls the sample standard deviation was found to be 0.52 pounds. Construct a 95% confidence interval for the variance of the bowling ball weight.
The mean math score for fifth grade students at Smart Elementary is 90 with a standard deviation of 8. The fifth grade students are tested each year to determine if the mean score remains the same.
For a hypothesis comparing two population means, what is the critical value for a one-tailed hypothesis test, using a 5% level of significance level, with both sample sizes equal to 13? Assume the population standard deviations are equal.
fourth group was divided into small discussion groups. A high of 10 was possible. A sample of five tests was selected from each group. The test grade results were: At the 0.01 level, what is the critical value?
Other group (drawing 6 slips without replacement from among 45). What is the probability that at least one of the shifts will be unrepresented in that sample of workers?
Supplier B's tires have an average life of 60,000 miles with a standard deviation of 2,000 miles. Which of the following statements is true?
Hospitials having fewer that 1000 discharges is estimated from a simple random sample of size 25. Use the central limit theorem to sketch the approximate sampling distribution of the estimate.
Evaluate and discuss the following hypothesis based on what you have learned about hypothesis statements. Should they be written differently, or are the sufficient the way they are stated?
If the total of the accounts receivable is only $1,000,000 (but the standard deviation was correct), what is the probability the total of the sample would be less than $9,900.
In order to compare the mean charges for the three groups, the data will be subjected to an analysis of variance. Write the null hypothesis tested by the ANOVA.
Is there a difference in the number of points students earned on their educational statistics pretests and posttests?
Define the population. State the hypotheses for the study. Decide which statistical test is appropriate and compute the test statistic (z or t). Why is the test appropriate?
