The success or failure of a new medical treatment is modeled as a Bernoulli trial with unknownprobability of success, p.A doctor treats one patient at a time, and will only treat the next patient if the previous patientresponds successfully.Suppose a doctor treats a total of n patients in this manner-stopping after the first failure occurswhen treating the nth patient. Hint: This is your data.What is the most likely value of p?In other words, find the maximum likelihood estimate p (in terms of n).

Number of trials = 45, Probability of success = 0.2. 4. Number of trials = 23, Probability of failure = 0.8. 5. Number of trials = 59, Probability of failure = 4/7.
A fast food restaurant just leased a new freezer and food fryer for three years. The service contract for the freezer offers unlimited repairs for a fee of $125 a year plus a $35 service charge for each repair needed. The restaurant's research indicates that during a given year 80% of these freezers need no repairs, 11% needed to be serviced once, 5% twice, 4% three times, and none required more than three repairs. What is the expected number of repairs for this freezer per year? a) 2.5 repairs b) 0.33 repairs c) 0.79 repairs d) 1.25 repairs
A medical researcher says that less than 80% of adults in a certain country think that healthy children should be required to be vaccinated. In a random sample of 300 adults in that country, 76% think that healthy children should be required to be vaccinated. At a=0.01, is there enough evidence to support the researcher's claim? Complete parts (a) through (e) below. When you know the number of successes x, the sample size n, and the population proportion p, it can be easier to use the formula shown below to find the standardized test statistic when using a z-test for a population proportion p. (a) Identify the claim and state H0 and Ha. Identify the claim in this scenario. Select the correct choice below and fill in the blank to complete your choice. (Type an integer or a decimal. Do not round.) A. The percentage of adults in the country who think that healthy children should be required to be vaccinated is not _______%. B._______% of adults in the country think that…
Determine whether the results below appear to have statistical significance, and also determine whether the results have practical significance. In a study of a weight loss program, 6 subjects lost an average of 49 lbs. It is found that there is about a 23% chance of getting such results with a diet that has no effect. (... Does the weight loss program have statistical significance? OA. Yes, the program is statistically significant because the results are unlikely to occur by chance. OB. Yes, the program is statistically significant because the results are likely to occur by chance. OC. No, the program is not statistically significant because the results are likely to occur by chance. O D. No, the program is not statistically significant because the results are unlikely to occur by chance. Does the weight loss program have practical significance? O A. No, the program is not practically significant because the amount of weight lost is trivial. O B. Yes, the program is practically…
A medical researcher says that less than 88% of adults in a certain country think that healthy children should be required to be vaccinated. In a random sample of 500 adults in that country, 85% think that healthy children should be required to be vaccinated. At a = 0.01, is there enough evidence to support the researcher's claim? Complete parts (a) through (e) below.

A gambler simulates a new card game on a computer. Out of 500 trials he wins 200 times. So he calculates P(winning) = 200/500 = 0.40. Why is this only an estimate of the true value of P(winning)? A. There are more than 2 events B. The outcomes are not equally likely C. His estimate is not rounded to 3 decimal places D. If he were to do a different set of 500 trials, he might win 180 times and calculate a different value of P(winning)
Will improving customer service result in higher stock prices for the companies providing the better service? "When a company's satisfaction score has improved over the prior year's results and is above the national average (currently 75.7), studies show its shares have a good chance of outperforming the broad stock market in the long run." The following satisfaction scores of three companies for the 4th quarters of two previous years were obtained from the American Customer Satisfaction Index. Assume that the scores are based on a poll of 67 customers from each company. Because the polling has been done for several years, the standard deviation can be assumed to equal 6 points in each case. Company Year 1 Score Year 2 Score Rite Aid 73 75 Expedia 72 75 J.C. Penney 73 74 a. For Rite Aid, is the increase in the satisfaction score from year 1 to year 2 statistically significant? Use a = .05 and null hypothesis is Ho : H1 – 42 <0. What can you conclude? z value (to 2 decimals) p-value (to…
Determine whether the results appear to have statistical significance, and also determine whether the results appear to have practical significance. In a study of a birth sex selection method used to increase the likelihood of a baby being born female, 1942 users of the method gave birth to 948 males and 994 females. There is about a 15% chance of getting that many babies born female if the method had no effect. Because there is a 15% chance of getting that many babies born female if the method had no effect, the method does not have statistical significance. Not many couples would likely use a procedure that raises the likelihood of a baby born female from the approximately 50% rate expected by chance to the 51.2 % produced by this method. (Round to the nearest integer as needed.) So, this method does not have practical significance.
