One hundred draws are made at random with replacement from box A, and 250 are made at random with replacement from box B. (a) 50 of the draws from box A are positive, compared to 131 from box B: 50.0% versus 52.4%. Is this difference real, or due to chance

Therefore WE accept the Null hypothesis That 50.0% versus 52.4%.difference is real

Step-by-step explanation:

Sample size A

Sample size B

Positive draw from box A

Positive draw from box b

Generally the equation for Probability of Positive draw from Box A is mathematically given by

Therefore

Generally the equation for Probability of Positive draw from Box A is mathematically given by

Therefore

Generally the equation for Standard error S.E is mathematically given by

Therefore

Generally

Therefore WE accept the Null hypothesis That 50.0% versus 52.4%.difference is real

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
