Recorded here are the germination times (in days) for nineteen randomly chosen seeds of a new type of bean. 18, 16, 11, 16, 18, 14, 13, 22, 12, 18, 21, 20, 21, 21, 22, 10, 15, 17, 22 Assuming that germination times are normally distributed, find a 99% confidence interval for the mean germination time for all beans of this type. Then find the lower limit and upper limit of the 99% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)
A random sample of 11subjects was asked to perform a given task. The time in seconds it took each of them to complete the task is recorded below. 49, 41, 44, 49, 39, 45, 47, 28, 36, 36, 41. If we assume that the completion times are normally distributed, find a 95% confidence interval for the true mean completion time for this task. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. Lower limit? Upper limit?
It is estimated that in the general population about 9 out of every 1000 or 0.009 children are diagnosed with autism. on study included 92 six month old babies who had a sibling with autism. twenty-eight of these babies were later diagnosed with autism. we will systematically construct a 99% confidence interval for the proportion of siblings of autistic children likely to have autism. What is the population being studied? What population parameter are we seeking to estimate? Describe this population parameter in words.
A random sample of 12 subjects was asked to perform a given task. The time in seconds it took each of them to complete the task is recorded below. 39, 39, 30, 41, 32, 34, 48, 27, 28, 38, 33, 32 If we assume that the completion times are normally distributed, find a 95% confidence interval for the true mean completion time for this task. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
A 95% confidence interval was calculated to be (15, 21). This means that if 100 such confidence intervals (CIs) were constructed, then 95% of the CIs will be (15,21) 95% of the CIs will include the population mean The population mean would lie between (15,21) 95 times. The population mean would be found in about 95 of the CIs.
Construct a 95% confidence interval for the true mean of city mileage (MPG) of all cars with a manual transmission. Assume that MPG of cars with a manual transmission follows a normal distribution. Also, provide an interpretation of the confidence interval in context. Here is my work so far Manual and Automatic Transmission Total # of Cars = 1129 Total # of Automatic Trans. = 877 Total # of Manual Trans. = 252 Average (Auto) = 18.97948 Average (Manual) = 20.69841 Standard Deviation (Auto) = 8.390146 Standard Deviation (Manual) = 8.565189 Automatic Min: 8 Q1: 15 Median: 18 Q3: 21 Mode: =MAX(B2:B878) = 126 Manual Min: 11 Q1: 18 Median: 20 Q3: 24 Mode: 31
Say we have a population parameter, and the 95% confidence interval for it is (-3, 10). Do you have evidence to conclude that the parameter is less than 11? Yes No
Decide if the following statement is true or false and explain your reasoning: Suppose you found a sample proportion p^p^and built a 95% and 99% confidence interval around it. If the the population proportion pp is in actually the 95% confidence interval, then it must also be in the 99% confidence interval.
