- What are requirements for testing a claim about a population mean with a known?define the terms population parameter, and sample statistics as they apply to statistical studies.Which statement is TRUE? Estimation is a procedure where a numerical value or values are assigned to the population parameter based on the information collected from a sample. Estimation is a procedure where numerical value or values are assigned to the sample statistic based on the information collected from a sample.
- a researcher uses an anonymous survey to investigate the television-viewing habits of 100 American adolescents. he plans to make infrence about tv habits and the american based survery the entire group of american adolescents is an example of? sample, population, parameter, and statistic?Supposed Wall Street securities firms claim that they paid out year end bonuses of an average of 95,000 per employee last year. we take a sample of employee at the ASBE securities firm to see whether the average year-end bonus is less than the report mean of 95,000 for the populations.The hypothesis test result only tells us whether there is a significant difference between 2 populations or not. Calculate the exact standardized effect size using the provided information.
- what is the predicted explanatory valueA crop researcher investigated the phenotypes that resulted from crossing two different types of cucumber plants. There are 4 possible resulting phenotypes (numbered 1, 2, 3, 4 in the data table below). Mendel's laws of genetic inheritance ('the model') suggest that the proportions should be 9/16, 3/16, 3/16 and 1/16 for phenotypes 1, 2, 3, 4 respectively. The classification of a sample of 1400 observations is given below together with the proportions suggested by Mendel's laws of inheritance (the model). Give the degrees of freedom that would be used in a test of whether or not the crossing results in a population that follows Mendel's laws of inheritance.
