the likelihood of an event happening. This value is always between 0 and 1. P(Event Happening) = Number of Ways the Even Can Happen / Total Number of Outcomes z score the number of standard deviations from the mean a data point is. Also known as a standard score z score lookup

Since the P-value 0.003 is less than the significance level 0.1, the results of the significance test are statistically significant. The interpretation of this is that the significance test offers ...

Since q = 1 - p, we have n(1 - p) = 10(1 - 0.4) nq = 10(0.6) nq = 6. Since np and nq are both not greater than 5, we cannot use the Normal Approximation to the Binomial Distribution. Calculate the mean μ (expected value) μ = np. μ = 10 x 0.4. μ = 4. Calculate the variance σ 2. σ 2 = np(1 - p) σ 2 = 10 x 0.4 x (1 - 0.4) σ 2 = 4 x 0.6. σ ...

Suppose that, the population of a bacteria colony changes according to P ( t ) = 8 e - 0.35 t (millions of bacteria ) hour (a) Find a formula for the population as a function of time, P ( t ) , if there are 9 million of bacteria at t = 0 hours. (b) Assume that the number of bacteria follows an exponential growth model: P(t) = P_0 e^(kt).

If a and b are two events where p(a) = 0.4, p(b) = 0 .6, and p(a and b) = 0.2, then what does p(b/a) equal? Assume that events A and B are independent. Show that events A and B^c are independent as well.

In a hypothesis test with hypotheses H_0: p = 0.26 and H_1: p \neq 0.2, a random sample of size 805 produced a sample proportion of 0.2550. The test is to be made at the 1% significance level. a. What are the critical values of z? b. What is the value o; Suppose for a particular hypothesis test, a = 0.04 and the P value = 0.05. Which of the ...
