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? O a. 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 b.Approximately 95% confident that the population mean deviation and sample sizes 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 O. 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 d. 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
