The heights of adult men in America are normally distributed, with a mean of 69.6 inches and a standard deviation of 2.66 inches. The heights of adult women in America are also normally distributed, but with a mean of 64.2 inches and a standard deviation of 2.56 inches. A. If a man is 6 feet 3 inches tall, what is his z-score (to two decimal places)? B. If a woman is 5 feet 11 inches tall, what is her z-score (to two decimal places)? C. Who is relatively taller?

Give the TI commands to find the mean, median, and standard deviation and compare to the original post when done by hand.  Mean = 14.1 + 6.4 + 9.6 + 21.2 + 16.8 + 2.2 + 6.0 = 76.3 / 7 = 10.9in. Median = 2.2, 6.0, 6.4, 9.6, 14.1, 16.8, 21.2 = 9.6in. How can I find the mean and median on TI caculator?

researcher would like to examine the effect of fertilizer on flower growth. She obtains several flowers. She randomly assigns half the plants to the no fertilizer condition. The other half of the plants receive fertilizer. She monitors their growth for a month. She then compares the amount of growth of the two sets of plants. Is there a difference in growth between the no fertilizer and the fertilizer conditions? Use the .05 level of significance. In addition, find Cohen’s d and state what the effect size is in a sentence. Growth Rating No Fertilizer 40,21,27,30, 47 Fertilizer 46,25, 24, 38, 53

According to a health foundation survey from 2018 and 2016, the average annual premiums for employer-sponsored health insurance for family coverage was $16,834 in 2018 and $15,745 in 2016. Suppose the survey for 2018, was based on 250 employees who had employer-sponsored health insurance and the survey for 2016 was based on 200 employees who had employer-sponsored health insurance. Assume the population standard deviation for 2018 and 2016 were $2160 and $1990; respectively. Find a 97% confidence interval for the mean difference. (Round your answer to 1 decimal place.)Lower limit = Upper limit =
