Using the simple random sample of weights of women from a data set, we obtain these sample statistics: n=50 and x-bar =150.09 lbs. Research from other sources suggest that the population of weights of women has a standard deviation given by o=30.83lbs. a) Find the best point estimate of the mean weight of all women. b) Find a 95% confidence interval estimate of the mean weight of all womena) The best point estimate is .b) The 90% confidence interval estimate is lbs< mu <lbs.

The triangles are similar. what is the value of x? show your work.

Tod does not have any cookies. david gives jeff 8 cookies. then he splits half of the cookies he has left with tod. david let’s c represent the number of cookies that he starts with. he finds the number of cookies that tod has is 1/2 the difference of c and 8. write an expression to represent the number of cookies that tod has.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
