Question Answered step-by-step Can you please help me these questions? 1. In constructing a confidence interval for the population mean using the t-distribution, we often need the degrees of freedom (df), confidence level, and the critical value.Use the Student t-distribution to determine the missing values in the table below.Report the positive t critical value accurate to 3 decimal places.SamplesizeDegrees offreedomConfidencelevelCriticalvalue (t) 17%2.89828 %1.314 995% 16 90%  2. If n=, ¯x=47, and s=3, construct a confidence interval at a 80% confidence level. Assume the data came from a normally distributed population.Give your answers to one decimal place._______ <µ< _______ 3.. The table below contains the birth weights in grams of 26 African American babies born at BayState Medical Center in Springfield, Massachusetts in 1986. Compute a 95% confidence interval for birth weight.DataWeight25022787291629622940295129353019303633493389343034023773385711471704194221052180231123672416237124542496Find the point estimate for the birth weights. Round your answer to 2 decimal places.Determine the value of tc. Round your answer to 5 decimal places.Find the margin of error for the confidence interval. Round your answer to 1 decimal place.Construct the confidence interval for birth weights. Enter your answer as an open interval of the form (a,b) and round to the nearest integer.­­­­­­­________.5. Babies weighing less than 2500 grams are considered to be of low birth weight. Can you conclude that the average birth weight is greater than 2500 grams?  a) No conclusions can be drawn since the confidence interval contains 25002500.b)Yes, the entire confidence is above 25002500.c)No, the entire confidence interval is below 25002500.
