Which of the following statements best describes the % confidence that the sample intervals in relation to the unknown population mean? Could we say that these samples are a good representative of the population mean? What other characteristics are evident in the samples? 10 9 6. O a. We could say that we are 99% confident that the sample intervals contain the value of the unknown population mean. This is a good representation of the unknown population . It's apparent that sample#4°s interval doesn't contain the population mean O b. There is about 90% confidence that the sample intervals contain the value of the unknown population mean. And this would imply that the sampling distribution is good representative of the population. All samples appear to have equal intervals thus their standard errors are equal O c. We are about 90% confident that the sample mean is within a certain distance of the unknown population mean. Increasing the sample sizes for all samples would decrease this interval and thus our % confidence will also decrease. However, this will improve the precision of estimating the population O d. Approximately 95% confident that the population mean is within the sample intervals, thus it's probable that this is a good representative of the population. All samples appear to have equal intervals implying equal standard deviation and sample sizes Sample

O a. We could say that we are 99% confident that the sample intervals contain the value of the unknown population mean. This is a good representation of the unknown
population mean. It's apparent that sample#4's interval doesn't contain the population mean
O b. There is about 90% confidence that the sample intervals contain the value of the unknown population mean. And this would imply that the sampling distribution is a
good representative of the population. All samples appear to have equal intervals thus their standard errors are equal
O c. We are about 90% confident that the sample mean is within a certain distance of the unknown population mean. Increasing the sample sizes for all samples would
decrease this interval and thus our % confidence will also decrease. However, this will improve the precision of estimating the population
O d. Approximately 95% confident that the population mean is within the sample intervals, thus it's probable that this is a good representative of the population. All
samples appear to have equal intervals implying equal standard deviation and sample sizes
