a) Calculate the probability that the weight of a randomly selected chocolate bar is less than 7.85 ounces. Be sure to: draw, label, and shade the distribution standardize z score find the area give answer in context

Describe the shape of the distribution. OA. It is skewed. O B. It is bimodal. O C. It is symmetric. O D. It is uniform.

Construct a stem-and-leaf display of the data.  What appears to be a representative strength  value? Do the observations appear to be highly  concentrated about the representative value or  rather spread out?  b. Does the display appear to be reasonably symmetric about a representative value, or would you describe its shape in some other way?  c. Do there appear to be any outlying strength  values?  d. What proportion of strength observations in this  sample exceed 10 MPa?  The strength data for beams is attached

Use the values on the number line to find the sampling error.   x=4.8 μ=5.61   The sampling error is=

Find the population mean or sample mean as indicated. Population: 8, 9, 11, 10, 7 Select the correct choice below and fill in the answer box to complete your choice. OA. x= OB. H=

Determine whether the statement is true or false. If it is false, rewrite it as a true statement. A statistic is a measure that describes a population characteristic. Choose the correct answer below. OA. True. B. False. A statistic is a measure that describes a sample characteristic. OC. False. A statistic is the science of collecting, organizing, analyzing, and interpreting data in order to make decisions.
