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

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it
