Which of the following individuals is likely to be excluded from a clinical trial?     An individual with other diseases besides the disease of interest.     An individual whose data is considered to be an outlier.     An individual of who is considered to be a minority.     An individual who will have difficulty complying trial protocols.    bartleby expert answers x2 is D (an individual who will have difficulty complying trial protocols); however, other online resources are consistently indicating A is actually the correct answer (an individual with other diseases besides the disease of interest)...which is the correct answer and why? thanks

How do I find the upper and lower limit?

What's the temperature? The temperature in a certain location was recorded each day for two months. The mean temperature was 80.8°F with a standard deviation 5.5°F. What can you determine about these data by using Chebyshev's Inequality with K = 3? At least % of the days had temperatures between °F and °F X

Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 678 randomly selected adults showed that 50.5% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim. The results v significantly v so there V sufficient evidence to support the claim that most adults would erase all of their personal information online if they could.

For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.  POP2014: 3072, 1989, 3794, 2689, 3211, 3722, 4385, 4009, 7598, 3862, 3097, 2726, 4881, 4157, 2570, 2512, 2518, 4863, 4147, 7139, 6067, 6819, 3705, 3239, 3824, 4977, 2576, 2940, 9791, 5231, 5634, 5337, 4205, 3888, 5562, 3335, 3770, 1808, 2045, 1532, 5420, 4993, 6109, 4377, 5424, 4976, 4507, 3738, 2827, 3485, 1559, 5199, 4702, 3971, 3803, 3356, 4670, 3816, 5477, 4760, 3126, 3630, 3755, 3795, 2578, 3382, 4005, 2442, 6096, 3799, 3843, 3836, 6046, 6431, 3561, 3142, 4829, 5058, 2471, 6119, 3523, 3094, 3146, 3356, 2618, 2366, 4266, 4016, 6080, 1554, 6878, 3645,…

#3 CI Mean The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 38.5 for a sample of size 22 and standard deviation of 8.4. Estimate how much the drug will lower a typical patient's systolic blood pressure (using an 80% confidence level). Assume the data is from a normally distributed population.   Enter your answer as a tri-linear inequality accurate to three decimal places.______ < μμ < _____

A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years, but with a smaller percentage of participants. One of these surveys estimates with 90% confidence that the mean household income in the U.S. falls between $69,709 and $69,917. Find the point estimate for mean U.S. household income. (Enter your answer as a whole number.) x = Find the error bound for mean U.S. household income. (Enter your answer as a whole number.) EBM =

K Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 41 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,765 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6,765 lb 41 Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 183.6 lb and a standard deviation of 35.4. The probability is approximately (Round to four decimal places as needed.) ONCORPURINE MIMPIETARTUST SAMPARADE HOMENOT MANCHEIDU WARMTPARASH PRES = 165 lb. What is the probability that the aircraft is overloaded?
