Answer 1

DETE 8 Claim bookstore The average textbook at Bc costs $ 62.35 . Ansi Ho: el=62.35 Ha: el 762.35 The null hypothesis would be. The average price of all textbooks from the store is $62.35. # n=60, X = 62.35, 6 =24 The point estimate 62.350 z* = 1.645 ME= 2* 6 Vn 1.645 x 62.35 Voo 13.241

lower limit= X-ME 62.35 -13.241 49.10g Upper limit= » tme = 62.35 +13.241 175.591 1. The 90°. С1 is 49.109 to 75.59) Based on this fail to reject the null hypothess
