Health care knowledge systems reported that an insured woman spends an average of 2.3 days in the hospital for a routine childbirth, while and uninsured woman spends an average of 1.9 days. Assume two samples of 16 women each were used in both samples. The standard deviation for the first sample in 0.6 day, and the other standard deviation of the second sample is 0.3 day. At the 0.01 significance level, test the claim that the means are equal.

On a cm grid, point p has coordinates (3,-1) and point q has coordinates (-5,6) calculate the shortest distance between p and q give your answer to 1 decimal place

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
