Identify the null and alternative hypothesis for the given scenario: The average bagel weight for bagels made in America is 8 oz. A true New Yorker claims the average bagel weight in NYC is much higher. 8 Ha:

Describe type I and type II errors for a hypothesis test of the indicated claim. A shoe store claims that no more than 25% of its new customers will return to buy their next pair of shoes. Describe the type I error. Choose the correct answer below. 16 OA. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is at least 0.25, but you reject Ho: p≥ 0.25. B. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is no more than 0.25, but you fail to reject Ho: p ≤ 0.25. C. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is at least 0.25, but you fail to reject Ho: p≥ 0.25. D. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is no more than 0.25, but you reject Ho: p≤0.25. Describe the type II error. Choose the correct answer below. O A. A type II…

bookstore costs $ 96.54. You want to test this claim. The null and alternative hypothesis in symbols would be: O Ho:u 2 96.54 H1: µ 96.54 O Ho:p = 96.54 H1:p + 96.54 O Ho:p 96.54 O Ho:u = 96.54 H1:µ + 96.54 O Ho:p > 96.54 H1:p < 96.54 The null hypothesis in words would be: O The average price of all textbooks from the store is $ 96.54 O The proportion of all textbooks from the store that are less than 96.54 is equal to 50% O The average price of textbooks in a sample is $ 96.54 O The average of price of all textbooks from the store is greater than $ 96.54. O The average of price of all textbooks from the store is less than $ 96.54. Based on a sample of 80 textbooks at the store, you find an average of 110.14 and a standard deviation of 12.8. The point estimate is: (to 3 decimals) (to 3 decimals) The 90 % confidence interval (use z*) is: to Rased on this we

1. The null hypothesis if you are trying to find out if you have enough evidence to conclude that the population means is different than 55 would be Ha: µ ≠ 55 True False 2. A p-value of 0.017 provides more evidence against the null hypothesis than a p-value of 0.005. True False
