The federal government would like to test the hypothesis that the average age of men filing for social security is higher than the average age of women set using alphaequals0.05 with the data below. if population 1 is defined as men and population 2 is defined as women, determine the 90% confidence interval for the difference in population means. men women sample mean 64.5 years 63.6 years sample size 35 39 population standard deviation 3.0 years 3.5 years a. (0.75, 1.05) b. (0.52, 1.28) c. (minus0.34, 2.14) d. (minus1.37, 3.17)

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
