A ______________ is a numeric measure computed from the sample data which is used to describe the sample and estimate the corresponding population parameter. If one were to measure the performance of runners in a race based on their finishing place, this would be an ______________ variable. If one were to measure the performance of runners in a race based on the time it took to complete the race, this would be a ______________ variable.

Answer #1

A __statistic__ is a numeric measure computed from the sample data which is used to describe the sample and estimate the corresponding population parameter. If one were to measure the performance of runners in a race based on their finishing place, this would be an __qualitative/ordinal___ variable. If one were to measure the performance of runners in a race based on the time it took to complete the race, this would be a __Qunatitiative/ratio____ variable.

In a controversial interview in April 2020, two Californian physicians used data they collected from their urgent care organization to argue in favor of reopening businesses, which were closed due to coronavirus. The urgent care organization runs several coronavirus testing sites around Kern County, California. The sites tested 5213 people by the time of this interview, which accounted for over half of the testing done in Kern County. Of those 5213 people, 340 tested positive for the coronavirus.

1) The process of inferring a population parameter from sample data is? 2) [x] is the probability distribution of values that might be obtained for an estimate of a population parameter. 3) The sample standard deviation (s) divided by the square root of the sample size (n) is the [x] 4 The [x] confidence interval provides a most-plausible range for a parameter.

To determine the proportion of cesarean sections among obstetrical deliveries in Baltimore, a random sample of histories was obtained from two obstetrical services: Johns Hopkins Hospital and University Hospital. The rate of cesarean sections for the sample was 20%. Later more complete information revealed that it was not indicative of the general experience throughout the city. Most hospitals in the city were found to have rates ranging from 10% to 12%. a) What is the target population for this study?...
