Math& 146 Name: Mia Hamilton Fall 2023 Worksheet 07, 50 points Content: Introductory Statistics, 9.1-9.3 Due: Tuesday, November 14 You may either turn this in at the end of class today (Tuesday, 11/14), or upload a pdf version of your worksheet to Canvas by 11:59pm tonight. Each problem is worth 10 points. Your final score will be scaled out of 50 points: points correct 40 × 50 Problems 1-2: Translate each of the following claims to their symbolic form using appropriate symbols and notation and write the symbolic form of the hull hypothesis and the alternative hypothesis. Indicate which hypothesis represents the claim. Clearly label each part. 1) Claim: The mean number of quarters required to complete a two-year degree is more than 6.3 quarters. M Clam M-6.3 AH red Ho: M≤ 6.3 A Hai M 6.3 Complement M≤6.3 null 2) Claim: Pecan pie is preferred by at least 60% of those who like pie. Claim P2 0.60 null Complement P2 0.60 Alt Hoop = 0.60 Haop < 0.60 Problems 3-4: Do the following for each claim and clearly label each part: a) Indicate which distribution should be used . b) State the random variable. c) Explain what the random variable means in this context. d) State the parameter. e) Explain what the parament is in this context. f) State the symbolic form of the claim, null hypothesis, and the alternative hypothesis. . g) State what the Type I error would be in this context h) State what the Type II error would be in this context. 3) Claim: More than 20% of those using Oxycontin experience side effects. a) Normal distiruktion C. The proportion Vample of those us @xycontin & experierse side a effects is more than 20%. 6) in the E) The poportion of all using Oxycontin Bexperiencing side, effects. F) Claim: p70.20 Null Ho: P≤ 0.20 HA: P70.20 G) A type lennor would be Concluding that marie than 20% of those usin e using, Oxycontin experience side effets, when in reality the proportion is 266 of less. type Il error would II be concluding theat 20% of less of those using Oxycontin experience side effects when in reality the proportions more than 20% Problems 3-4: Do the following for each claim and clearly labeteach a) Indicate which distribution should be used b) State the random variatile c) Explain what the random variable means in this conten d) State the parameter e) Explain what the parament is in this context f) State the symbolic form of the claim, null hypothesis, and hy 9 ) State what the Type I error would be in this context h) State what the Type II error would be in this content 4) Claim: The (nean life span of fruit flies is at most 254 days a) t * 637. C .) The mean, life span of fried files. 9 m E) The mean lifespan of all fruit fles f) Chim: M≤ 25.4 Complement: M=25.4 Ho: m ≤ 25.4 Cclain) HAM > 25.4 G) Type I Error: Reject the mean lifespar of fruit flies is at man most 25.4 Days when it actually at Most 25.4 Days. Reject the mean lifespan of fruit flies is is 254 days. 26.4 daye it really when it really #Type II Error: Fail to reject that the mean is lifespan of fruit files 25.4 days when it is actually greater than 25 days
