The area under the density curve that lies to the left of 10 is 0.654. What percentage of all possible observations of the variable are a. less than 10? b. at least 10?
Added by Gloria P.
Step 1
The area under the density curve to the left of 10 represents the percentage of observations less than 10. Since the area is 0.654, the percentage of observations less than 10 is: $0.654 \times 100\% = 65.4\%$ b. Show more…
