(d) What is the probability that i 27 more people or more have a luat namb ining with the same letter Explain the principle in detail which allows you to conclude this The resting heart rate for dogs follows a distribution with mean 1 15 beats permite and standard deviation 12 boste per minute la X denote the resting heart rate of random dos Compute (A) P(X>120) (Compute in two ways) (1) P(95 SX S125) () PCX 150) (1) Find the 70th percentile X (e) According to Chebyshev's Rule, what percent of heart rate le between 91 and 1397 What is the actual percent In the following me you spin a wheel with ten equally sin regions labelled: A, B, C, D, E, F, G, HLJ. If the wheel stop at G, the player wins $80. If the wheel tops B, C, or the player wins $40. If the wheel stops at any other member, the player loses $15. (a) Construct a probability distribution table for this wheel (b) Compute the expected value E(X) for this game (c) Compute the standard deviation ex (d) If you play 25 times, how much do you expect to win or lose? 10. The man weight of women in a high school is = 140 lbs. The standard deviation is 24 lbs. A sample of 35 students is chosen Calculate: (A) PT> 14) (b) P[132 <1 <148) 11. A random sample of 144 people was taken. The average body temperature (the sample mean ) calculated to be 98 25 F and the standard deviation for the population is known to be 0.6 F. We wish to estimate the unknown population mean (a) Computea 90% confidence interval for and compute its width (1) Computea 99% confidence interval for and compute its width (c) Which interval is a more precise estimate? Explain (d) How large of sample should one choose to guarantee the margin of error from Part (a) at 99 (e) Suppose now that the population standard deviation is unknown but that for a sample of 10 people, 1 985 P and the sample standard deviation 0.7 F Computea 97% confidence Do the data in Part le provide sufficient evidence to reject the claim that 98.6 F at the 1% Jewel of nificance? Explain. Asume sample of 10 people and a sample standard deviation of 0.7 F. Compute 99% confide interval for the wall and the tandard deviation in Part (a)? cigarettes is advertised as having a mean nicotine content of 15 mg/cigarette. A ittes was tested and found to have an average of 16.2 mg of niorting and a standard

I need the answer for 11 f and g. thanks

Answer 1

V10 (f) 99% of for mean is (& & ton & J) = ( 9825 0.005 0.7) I 3.250 0.7 10 = (98.25 I 0.72) = (97.53, 98.97) u=98 E (97.53, 9897) so the data does not show sufficient evidence to reject Ho at 1% level (9) (04) 5 xn- PL X-45 (n-1) s < x- 1- PI (2-1) 52 <o< (1) 52 ]-ta. Xn-1, 1-0 so 99% (.I for 6² is 23.6 (ex 07, 9x072 ) =(-1868,2-5491) 39 ct for is (1 9x07 V ) = (0.4316) [x3, 0.005 23:6, x2, 0995= 1:73].
