A low-risk 24-week primagravida client is curious about sexual activity and her pregnancy. The nurse’s best response would be:

Fayech University claims that the mean GPA of night students is approximately normally distributed with mean 3.3 with a population standard deviation of 0.04. We wish to test the claim that the mean GPA of night students is significantly different than 3.3 at the 0.05 significance level.  Based on a sample of 55 people, we find the sample mean GPA was 3.33. The null and alternative hypothesis would be: [a] Type the letter of the correct option in the box above. A B C D E F The test is: [b] Type the letter of the correct option in the box above. A B C two-tailed left-tailed right-tailed The test statistic is [d] (to 2 decimals) The critical value is:  [e] (to 2 decimals) Draw a picture of this graph on your scratch paper.  I will grade the graph after you upload your work. [c] Based on this we [f] A B Fail to reject the null hypothesis Reject the null hypothesis  

Find the area of the shaded region under the standard normal distribution to the right of the given z-score. Round your answer to four decimal places.  

 It has been reported that 9 % of phones manufactured by a certain company for a product launch did not meet the quality standards. An engineer needs at least one defective Phone so she can try to identify the problem(s). If she randomly selects 13 phones from a very large batch, what is the probability that she will get at least 1 that is defective? Is that probability high enough so that she can be reasonably sure of getting a defect for her work? Probability that at least one phone out of a sample of 13 is defective is (round to 4 decimal places). [a] Is the probability high enough so that she can be reasonably sure of getting a defect for her work? Type Yes or No in the box below.  [b]

A rancher is interested in the average age that a cow begins producing milk. Match the vocabulary word with its corresponding example.  

Read and answer the following question. If a calculation is not possible, type NA. The population of weights for men attending a local health club is normally distributed with a mean of 183 lbs and a standard deviation of 26 lbs. An elevator in the health club is limited to 35 occupants, but it will be overloaded if the total weight is in excess of 6860 lbs.Assume that there are 35 men in the elevator. What is the average weight per man that, beyond which, the elevator would be considered overloaded? average weight = [a] lbs What is the probability that one randomly selected male health club member will exceed this weight? P(one man exceeds) = [b] round to 2 decimal places If we assume that 35 male occupants in the elevator are the result of a random selection, find the probability that the elevator will be overloaded? P(elevator overloaded) = [c] round to 4 decimal places

A group was tested for drugs. The table shows the results of the test along with actual drug use. Test Positive Test Negative Total Used Dugs 26 13 39 No Drug Use 25 189 214 Total 51 202 253 Let D = event “Used Drugs”, N = event “No Drug Use”, + be “Test positive”, and finally – be “Test negative”Round each answer to 4 decimal places. (D or +)= [a] (N and +) = [b] (N 

Read and answer the following question. If a calculation is not possible, type NA. The population of weights for men attending a local health club is normally distributed with a mean of 182 lbs and a standard deviation of 30 lbs. An elevator in the health club is limited to 34 occupants, but it will be overloaded if the total weight is in excess of 6698 lbs.Assume that there are 34 men in the elevator. What is the average weight per man that, beyond which, the elevator would be considered overloaded? average weight = [a] lbs What is the probability that one randomly selected male health club member will exceed this weight? P(one man exceeds) = [b] round to 2 decimal places If we assume that 34 male occupants in the elevator are the result of a random selection, find the probability that the elevator will be overloaded? P(elevator overloaded) = [c] round to 4 decimal places
