Cαlculαte the 95% cοnfidence intervαl fοr the difference (mu1-mu2) οf twο pοpulαtiοn meαns given the fοllοwing sαmpling results. Pοpulαtiοn 1: sαmple size = 13, sαmple meαn = 33.74, sαmple stαndαrd deviαtiοn = 4.52. Pοpulαtiοn 2: sαmple size = 9, sαmple meαn = 16.28, sαmple stαndαrd deviαtiοn = 3.04.

A vitamin K shot is given to infants soon after birth. Nurses at Northbay Healthcare were involved in a study to see if how they handle the infants could reduce the pain the infants feel ("SOCR data nips," 2013). One of the measurements taken was how long, in seconds, the infant cried after being given the shot. A random sample was taken from the group that was given the shot using conventional methods (first table), and a random sample was...

Given two independent random samples with the following results: n1=9    n2=13 x‾1=153 x‾2=113 s1=30    s2=26 Use this data to find the 95% confidence interval for the true difference between the population means. Assume that the population variances are not equal and that the two populations are normally distributed. Copy Data Step 2 of 3 : Find the margin of error to be used in constructing the confidence interval. Round your answer to six decimal places.

Use forward and backward difference approximations of O(h) and a centered difference approximation of O(h^2 ) to estimate the first and second derivatives of f(x)= 0.4x^5 ‐0.2x^3 +6x^2 ‐13 at x=2 using a step size h=1. Repeat the computation using h values of 0.5, 0.25, and 0.1. Compare your results with the exact derivative value at x=2.
