- The confidence interval is: Question 18 options: a range of values around a point estimate between its upper and lower confident limits that the population parameter falls. a range of values around interval estimates between its upper and lower confident limits that the population parameter falls a relative frequency of values around interval estimates between its upper and lower confident limits that the population parameter falls a relative frequency of values around a point estimate between its upper and lower confident limits that the population parameter fallsTwo samples of sizes 25 and 35 are independently drawn from two normal populations, where the unknown population variances are assumed to be equal. The number of degrees of freedom of the equal variances t-test statistic is: А. 58 В. 35 С. 59 D. 60A confidence interval for a mean is (−13,14)-13,14. This interval would be wider if A.)The sample mean was larger or the variability of the data was larger. B.) The variability of the data was larger, or the investigator wanted to be more confident. C.) The investigator wanted to be more confident of their results, or there was more information. D.) The variability of the data was small, or the sample mean was larger. E.) None of the above.
- Express the confidence interval 76.1 % + 7.9 % in the form of a trilinear inequality. %Please show work on paper pleaseExplain what "98% confidence" means in a 98% confidence interval, What does "98% confidence" mean in a 98% confidence interval? O A. If 100 different confidence intervals are constructed, each based on a different sample of sizen from the same population, then we expect 98 of the intervals to include the parameter and 2 to not include the parameter. O B. The probability that the value of the parameter lies between the lower and upper bounds of the interval is 98%. The probability that it does not is 2%. O C. The confidence interval includes 98% of all possible values for the parameter. O D. The value of the parameter lies within 98% of a standard deviation of the estimate.
