Estimation
A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.
Question
A). A COMPANY IS CONDUCTING AN ONLINE SURVEY OF RANDOMLY SELECTED INDIVIDUALS TO DETERMINE HOW FREQUENT THEY RECYCLE. SO FAR, 2451 PEOPLE HAVE BEEN SURVEYED. THE FREQUENCY DISTRIBUTION SHOWS THE RESULTS. WHAT IS THE PROBABILITY THAT THE NEXT PERSON SURVEYED RARELY RECYCLES? RESPONSE NUMBER OF TIMES, f Always 1054 Often 613 Sometimes 417 Rarely 196 Never 171 Total = 2451 B). USE THE CONCEPT OF COMPLEMENTARY EVENTS TO DETERMINE: IF THE PROBABILITY OF A PERSON GETTING SICK IS 5/9. WHAT IS THE PROBABILITY OF THE SAME PERSON NOT GETTING SICK? USE THE FORMULA: P(SICK) + P (NOT SICK) = 1
