Assume that you plan to use a significance level of α = 0.05 to test the claim that p1 = p2, use the given sample sizes and numbers of successes to find the pooled estimate p. round your answer to the nearest thousandth.
n1 = 100 n2 = 100
x1 = 42 x2 = 49

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with

Ascientist has 50 grams of a radioactive element. the amount of radioactive element remaining after t days can be determined using the equation (1) after two days the scientist receives a second shipment of 50 grams of the same element. the equation used to represent the amount of shipment 2 remaining after t days is 10) - 50 which of the following is an equivalent form of the expression for the amount remaining in shipment 2? what’s the answer?

How do you find p(a and b) if a and b are independent events for two or more actions, such as tossing a coin twice and finding p(heads and heads)? 2. how do you find p(a or b) if a and b are independent events for one action, such as spinning a four-color spinner once and finding p(red or blue)?
