One outcome is called __________ , and the other is called ___________.If a binomial experiment has probability p success, then the probability of failure is ____________________. The probability of getting exactly r successes in n trials of this experiment is C(_________, _________)p (1p)A group of doctors is deciding whether or not to perform an operation. Suppose the null hypothesis, H0, is: the surgical procedure will go well. Which is the error with the greater consequence?
- Q3. If the null hypothesis is not rejected when the null hypothesis is in error, what type of error, if any, has been made?The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 50 records of automobile driver fatalities in a certain county showed that 33 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County? Use ? = 0.10. State the null hypothesis H0 and the alternate hypothesis H. np? nq? What is the value of the sample test statistic? (Round your answer to two decimal places.) Find the P-value of the test statistic. (Round your answer to four decimal places.) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level ?? Interpret your conclusion in the context of the application.Use the Null hypothesis to answer the following question What would the alternative hypothesis be?

Make a null hypothesis and alternative hypothesis on the following research situations: a) To study how the English writing skills of pupils whose language teacher followed a new teaching strategy compare with those pupils whose teacher followed the traditional strategy.In a recent sample of 250 households, 45% of them owned a video game console. A hypothesis test was performed using the following hypotheses: Họ : p = 0.40 vs. H, : p> 0.40. A Type II error for this hypothesis test is: To conclude that 40% of households own a video game console when, in reality, it is more than 40%. To conclude that 40% of households own a video game console when, in reality, it is equal to 40%. To conclude that r than 40% of households own a video game console when, in reality, it is more than 40%. To conclude that more than 40% of households own a video game console when, in reality, it is equal to 40%.
