Suppose that BC financial aid allots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 57.8. You want to test this claim. The null and alternative hypothesis in symbols would be: O Ho:p > 57.8 H1:p 57.8 H1:µ 57.8 O Ho:p 57.8 O Ho: u = 57.8 H1: µ # 57.8 O Ho:p = 57.8 H1:p 57.8 The null hypothesis in words would be: O The average price of all textbooks from the store is $ 57.8 O The average price of textbooks in a sample is $ 57.8 O The proportion of all textbooks from the store that are less than 57.8 is equal to 50% O The average of price of all textbooks from the store is greater than $ 57.8. O The average of price of all textbooks from the store is less than $ 57.8. Based on a sample of 70 textbooks at the store, you find an average of 54.2 and a standard deviation of 29.6. The point estimate is: (to 3 decimals) The 95 % confidence interval (use z*) is: to (to 3 decimals) Based on this we: ATM hp
A formula is self-contradictory when . . . Select one or more: a. it has no model. b. it is false on every interpretation of it. c. there is no interpretation on which it is true. d. it is true on some interpretations and false on others. e. it is false on at least one interpretation.
+N a) A 4 of Hearts? C w b) A Heart or Spade? W +4 → of > > ♥ above, As shown a classic deck of cards is made up of 52 cards, 26 are black, 26 are red. Each color is split into two suits of 13 cards each (clubs and spades are black and hearts and diamonds are red). Each suit is split into 13 individual cards (Ace, 2-10, Jack, Queen, and King). + If you select a card at random, what is the probability of getting: (Round to 4 decimal places where possible) c) A number smaller than 9 (counting the ace as a 1)?

Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 60.92. You want to test this claim.The null and alternative hypothesis in symbols would be: a) H0:p≤60.92H1:p > 60.92 b) H0:μ=60.92; H1:μ≠60.92 c) H0:μ ≥ 60.92; H1:μ < 60.92 d) H0:μ ≤ 60.92; H1:μ > 60.92 e) H0:p≥60.92; H1:p<60.92 f) H0:p=60.92; H1:p≠60.92 The null hypothesis in words would be: The average price of all textbooks from the store is $$ 60.92 The average price of textbooks in a sample is $$ 60.92 The average of price of all textbooks from the store is less than $$ 60.92. The proportion of all textbooks from the store that are less than 60.92 is equal to 50% The average of price of all textbooks from the store is greater than $$ 60.92.
