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 nomal sampling distribution and shade the area for the P-value. A report claims that lung cancer accounts for 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 (1). The null hypothesis is expressed symbolically as Ho: (3) p(2) - (Type integers or decimals. Do not round.) gyt un e nn of State the alternative hypothesis in words and in symbols. (0) ot soge The alternative hypothesis expressed in words is the proportion of cancer diagnoses attributable to lung cancer (3) The alternative hypothesis is expressed symbolically as Ha:
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
