The test statistic of z = - 3.07 is obtained when testing the claim that p <0.48. a. Using a significance level of a = 0.01, find the critical value(s). b. Should we reject H, or should we fail to reject Ho? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. The critical value(s) is/are z = (Round to two decimal places as needed. Use a comma to separate answers as needed.) b. Choose the correct conclusion below. O A. Reject Ho. There is not sufficient evidence to support the claim that p< 0.48. O B. Fail to reject Ho. There is sufficient evidence to support the claim that p< 0.48. O C. Fail to reject Ho. There is not sufficient evidence to support the claim that p< 0.48. O D. Reject Ho. There is sufficient evidence to support the claim that p< 0.48.

Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.

Normal Distribution

Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
