- SHOW ALL WORK. Interpret confidence intervals and explain the conclusions from hypothesis tests. For all hypothesis tests, clearly state the null and alternative hypotheses, the significance level, the test statistic, the p-‐value, and your conclusion. If you are using a t-statistic, clearly note how many degrees of freedom you have. 1. Consider the following data collected regarding infant blood pressure, age, and birth weight: i Birth weight in oz. (x1) Age in days (x2) Systolic Blood Pressure mmHg (y) 1 135 3 89 2 120 4 90 3 100 3 83 4 105 2 77 5 130 4 92 6 125 5 98 7 125 2 82 8 105 3 85 9 120 5 96 10 90 4 95 11 120 2 80 12 95 3 79 13 120 3 86 14 150 4 97 15 160 3 92 16 125 3 88 A. Interpret the corresponding 95% confidence intervals for both Birth weight and Age. B. What is the predicted average SBP of an infant born with birth weight 8lbs (128oz) measured at 3 days old? C. Calculate the Pearson correlation between Age and Birth weight, and test if this correlation is…You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Your sample size is 8. While it is an uncommon confidence level, find the critical value that corresponds to a confidence level of 93.5%.Use the given information to find the number of degrees of freedom, the critical values y? and y?, and the confidence interval estimate of o. It is reasonable to assume that a simple random sample has been selected from a population with a normal distribution. Platelet Counts of Women 90% confidence; n= 23, s = 65.4.

- Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t/2, (b) find the critical value z,/2, or (c) state that neither the normal distribution nor the t distribution applies. 230, x 32.6 hg, s = 7.9 hg. The confidence level is 90% Here are summary statistics for randomly selected weights of newborn girls: n Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
