Fawns between 1 and 5 months old have a body weight that is approximately normally distributed with mean ? = 29.7 kilograms and standard deviation ? = 4.4 kilograms. Let x be the weight of a fawn in kilograms. Use the graph uploaded for reference.    Convert the following z intervals to x intervals. (Round your answers to one decimal place.) fill in the blank.   a) −2.17 < z,  ______ < x b) z < 1.28,  x < _______ c) −1.99 < z < 1.44,  _________< x < _______

Q1. A study was conducted to investigate the relationship between premature birth and mental development at 12 months. The infant's birth weight was used as an index of prematurity. At age 12 months, the child's mental development was recorded. The results are shown below (the weights are in pounds): Birth 4 6 7 8 Weight(x) Developmental 85 Quotients(y) 88 87 94 96 Summary: n = 5, £x=30, £x² = 190, Ey= 450, Ey² = 40590, Exy = 2728 . a. Find the least square prediction equation, y on x. b. Obtain a 95% confidence interval for the average value of y when x 6.5 (i.e., a C.I. for E(y|x= 6.5)). c. Obtain the coefficient of correlation (r) and interpret the result. d. Test the hypothesis that H, :p= 0 vs. H, : p0. Use a =0.05.

Coefficient of variation is measure of dispersion. Select one: a. absolute b. relative C. Both of these d. none of these

Find the z-score corresponding to the given value and use the z-score to determine whether the value is significantly low or high.  Consider a score to be significantly low if its z-score is less than  or equal to -2.  Consider a z-score to be significantly high if it is greater than or equal to 2.  Round the z-score to the nearest tenth if necessary. A body temperature of 96.7° F given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°.
