The national average on a reading test is 72. The average for a sample of 80 students in a certain geographical region who took the exam is 70. Is the average test score for students in this region statistically different from the national average? Find the P-value for the test. Assume a population standard deviation of 13.

A) 0.0419

B) 0.0210

C) 0.3352

D) 0.1676

E) 0.0838

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.

step-by-step explanation:

32.50-7.50=25

225/25=11

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
