8. <

9. =

10. >

11. >

12. >

Step-by-step explanation:

5. 9.33 x 10³ = 9330

9330 > 933

6. 2.88 x 10⁻⁵ = 0.0000288

2.9 x 10⁻⁶ = 0.0000029

0.0000288 > 0.0000029

7. 0.33 x 10⁻⁷ = 0.000000033

3.7 x 10⁻⁶ = 0.0000037

0.000000033 < 0.0000037

8. 4.9 x 10⁴ = 49000

4.79 x 10⁵ = 479000

49000 < 479000

9. 3.0 x 10⁶ = 3000000

30 x 10⁵ = 3000000

3000000 = 3000000

10. 2.2 x 10⁻³ = 0.0022

1.7 x 10⁻³ = 0.0017

0.0022 > 0.0017

11. 2.1 x 10⁷ = 21000000

2 million = 2000000

21000000 > 2000000

12. 5.2 x 10¹¹ = 520000000000

8.7 x 10¹⁰ = 87000000000

520000000000 > 87000000000

It is believed that 43% of the US population can play the piano, 28% can play the guitar, 15% can play the harmonica, 12% can pl
LenaWriter [7]

43% = 'Piano'

28% = 'Guitar'

15% = 'Harmonica'

12% = 'Drums'

2% = ...Other Instruments

- '2' Does seems as to be the <u>smallest</u> but it could be a trick.

- '43' Is the largest percentage out of the whole group.

- '100' Is what you get when you add all of the percentages together.

- And if you try to evaluate the percentages together in either way it'll end up to be '0.00004334' so that executes '250' and '150' from out of the question.

I'm not sure exactly what the actual answer could be but I'm assuming since it said "What is the smallest number of people required for the sample to meet the conditions for performing inference" Then my assumption is '2'.
