I NEED HELP ASAP A store sells ground meat in small, medium, and large sizes. The weights of the small size packages have a mean weight of 1 pound and a standard deviation of 0.1 pound.

If the distribution of weights for the small size packages of ground meat is approximately normally distributed, which of the following is the best estimate of the probability that a randomly selected small size package has a weight less than 0.9 pound?

A
0.023

B
0.68

C
0.16

D
0.32

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31 ,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28 ,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b. the means of the data sets are within 3 units from eachother. c. the data sets have the same standard deviation. d. the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.

Lola says these two expressions have the same value. expression a expression b which explains whether lola is correct?
