Hello I need help solving this statistics question that I am struggling with. Thank you for any help!

Drugs must undergo thorough testing byme being approved Is there sufficient evidence to support the for general use. In addition to testing for adverse reactions, claim that the dung lowers plate rates at They must also be tested for effectiveness. Consider the development of a new dung to lower pulse rates. The ding * = 105 ? Is tested using makes only. Below are the pulse rates for a ( b) Is there a a better way to measure the drugs placebo group, group of men treated is/ 10 my doses of the drug, and a group of men treated wl 20 my doses of the day, effectiveness in lowering pulse rates? What Kind The project manager, finds that for adult males in general, pulse rates are normally distributed wl mean 70 beats pu of experimental design would you use of why? minute and a standard deviation of approx 11 beats perminute. His summary report states that the drug is effective, based on the cadence that the placebo group has a mean pulse of 68. 9 beats per minute while the groups treated wl 10ms + 20 mg doses have a mean pulse rate of 66-2 2 65.2 beats pu minute respectively. use the data below to answer the following questions : placebo group : 77 61 1 66 1 63 81 75 66 79 /66 75 148 710 10mg treatment group : 67 48 79 67 /57 /71/ 66 85 75 77 /57 45 long treatment group : 72 94 57 63 69 59 / 64 82 34 76 59 53
