In order to monitor the ecological health of the Florida Everglades, various measurements are recorded at different times. The bottom temperatures are recorded at the Garfield Bight station and the mean of 30.4 C is obtained for 61 temperatures recorded on 61 different days. Assume a population standard deviation of 1.7 C , test the claim that the population mean is greater than 30.0 C . Use a 0.10 significance level. Decide whether to reject or fail to reject the null hypothesis and state your conclusion. You would [Select] [Select ] population mean is greater than 30.0 C .

Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 21 , upper bound is 29 . The point estimate of the population mean is 1

A survey of 2283 adults in a certain large country aged 18 and older conducted by a reputable polling organization found that 406 have donated blood in the past two years.

Determine whether the following statement is true or false. To construct a confidence interval about the mean, the population from which the sample is drawn must be approximately normal. This statement is

Homework Determine the point estimate of the population proportion, the margin of error for the following confidence interval, and the number of individuals in the sample with the specified characteristic, \( x \), for the sample size provided. Lower bound \( =0.529 \), upper bound \( =0.831, n=1500 \) (Round to the nearest thousandth as needed.) The margin of error is \( \square \). (Round to the nearest thousandth as needed.)
