The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean , the actual temperature of the medium, and standard deviation o. LAUSE SALT What would the value of a have to be to ensure that 95% of all readings are within 0.2° of u? (Round your answer to four decimal places.) 6= You may need to use the appropriate table in the Appendix of Tables to answer this question.

Heights for group of people normally distributed with mean = 63 inches and standard deviation = 2.6 inches. Find the height, h such that about 10% of people in the group are shorter than that height. (Round the answer to the nearest tenth.)h = in.What is the percentile, p ranking for that height? p = % You may need to use the appropriate table in the Appendix of Tables to answer this question.

Determine whether the given value is a statistic or a parameter. A homeowner measured the voltage supplied to his home on a random sample of 48 days, and the average (mean) value is 122.9 volts. Choose the correct answer below. OA. The given value is a statistic for the year because the data collected represent a sample. OB. The given value is a parameter for the year because the data collected represent a population. OC. The given value is a parameter for the year because the data collected represent a sample. OD. The given value is a statistic for the year because the data collected represent a population.

please show the step by step solution and provide an explanation on why that is the right answer.
