Step-by-step explanation:
Form a table as shown
Months Teddy Bears Rabbits Cats Horses Others Totals toys
September 225 275 245 260 199 1204
October 346 308 186 297 285 1422
Trends
Cats decreased from 245 to 186
Others increased from 199 to 285,
285-199 = 86
percent increase was = increase/original quantity *100
86/199 *100 =43.22%
Total number of stuffed toys increased from 1204 to 1422

Answer:
25.5 days
Step-by-step explanation:
Mean number of days (μ) = 22 days
Standard deviation (σ) = 6 days
Z-score for the 72nd percentile (according to tabulated values) = 0.583
The z-score for any number of days, X, is determined by:
The value of X that is greater than 72% of the trial times is:
Therefore, 72% of all of these types of trials are completed within 25.5 days.
Function: 12+0.5x
12+0.5x=18.5
0.5x=6.5
x=13 days
