The statements of a talking robot ‘Rufia’ are either true or false. The probability of a statement being false is 30.0% . Suppose, there are 20 random statements made by Rufia in a specific interview. a. What is the mean number of false statements given by Rufia in that interview? b. What is the standard deviation in the number of false statements? c. What is the probability that the number of false statements is more than 2 standard deviations away from the mean value? Note: Answer in exact fraction, or rounded to at least 2 decimal places.

Suppose, you are running an experiment that has two outcomes, namely 'success' and 'failure'. You intially don't know the probability of success in a single experiment. But you know that, if you continue to run the experiment several times, the expected number of experiment required for the first success is 8. What is the standard deviation of the number of experiments required for the first success? In details.
8. An HP laser printer is advertised to print text documents at a speed of 18 ppm (pages per minute). The manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.57 ppm and a standard deviation of 3 ppm. A Brother brand printer can print an average of 17.21 ppm and a standard deviation of 4 pages and its printer speed is also normally distributed. You select 10 of each printer at random. What is the probability that mean Brother print speed is at least 2 pages faster than the mean HP print speed?
The 3-point shooter star of your favourite team usually attempts twelve 3-point shots in a basketball game. The team record shows that the shooter makes 45% of all 3-point shots attempted in a game. Assuming that the shots are independent of each other,what is probability that the star will make shots at least 2 standard deviation more than the expected?
According to College Board, the average out-of-state tuition for a four-year public college was $8,893 for the 2013-2014 academic year. There are a total of 629 four-year public institutions in the U.S. Assume that the standard deviation for the tuition for these colleges is $950. A random sample of 60 four-year public colleges was selected. What is the probability that the average tuition from this sample is less than $9,000?

According to a survey, 10% of Americans are afraid to fly. Suppose n=1052n=1052 Americans are sampled. While computing standard deviation, use either at least 6 places or even better is to use the exact value. What is the probability percentage that 121 or more Americans in the survey are afraid to fly? Round the percent to two decimal places. What is the probability percentage that between 101 and 165 (inclusive) Americans in the survey are afraid to fly? Round the percent to two decimal places.
For runners competing in a marathon, the mean time to run a mile is 4.2 minutes with a population standard deviation of 0.6 minutes. A news reporter is looking to include statistics for his article about fast runners. At a marathon, a random sample of 31 runners was taken and the probability that the mean time to run a mile for the sample will be less than 3.9minutes was found. Was the probability a left-tail, right -tail or two-tail probability? What is the probability that the mean time to run a mile for the sample will be less than 3.9 minutes? Select the two correct answers that apply below. You may use a calculator or the portion of the z-table given below. Round your answer to three decimal places if necessary.
About 77% of all female heart transplant patients will survive for at least 3 years. Eighty female heart transplant patients are randomly selected. What is the probability that the sample proportion surviving for at least 3 years will be less than 69%? Assume the sampling distribution of sample proportions is a normal distribution. The mean of the sample proportion is equal to the population proportion and the standard deviation is equal to The probability that the sample proportion surviving for at least 3 years will be less than 69% is (Round to four decimal places as needed.)
Among all monthly bills from a certain credit card company, the mean amount billed was $465 and the standard deviation was $300. In addition, for 15% of the bills, the amount billed was greater than $1000. A sample of 850 bills is drawn. What is the probability that more than 150 of the sampled bills are for amounts greater than $1000? Probability =
The length of human pregnancies from conception to birth is approximately Normal with a mean length of 266 days and a standard deviation of 16 days. What is the probability that the average pregnancy length for 7 randomly chosen women exceeds 270 days?
Listed below are the summaries of the scores of two basketball players coming from two competing teams in the finals in the 20 games they played during the entire season. Who is the better player in terms of the scores? Player 1 Player 2 Mean 23 23 Standard Deviation 4.94 3.13 No conclusion can be made on who scores better, since the mean scores are equal. Player 2 scores better than Player 1 since Player 1 has a higher standard deviation. Player 1 scores better than Player 2 since Player 1 has a higher standard deviation. Player 1 scores better than Player 2 since Player 2 has a lower standard deviation.
