State Ho and H, in words and in symbols. Then determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Explain your reasoning. Sketch a normal sampling distribution and shade the area for the P-value. A report claims that lung cancer accounts for at least 23% of all cancer diagnoses. State the null hypothesis in words and in symbols. The null hypothesis expressed in words is the proportion of cancer diagnoses attributable to lung cancer The null hypothesis is expressed symbolically as Họ: p (Type integers or decimals. Do not round.) State the alternative hypothesis in words and in symbols. The alternative hypothesis expressed in words is the proportion of cancer diagnoses attributable to lung cancer The alternative hypothesis is expressed symbolically as Ha: p ▼ (Type integers or decimals. Do not round.) The hypothesis test is because the alternative hypothesis contains
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!
