The randNorm function in the TI-83 was used to generate the following 50 numbers with a mean of 75 and standard deviation of 5. Use the empirical rule, a histogram, and a normal quantile plot to determine if this data could have come from a normal distribution. Explain clearly how each of these tools provide evidence for your conclusion. The data:
66, 66, 67, 68, 68, 68, 70, 70, 70, 71
71, 71, 72, 73, 73, 73, 73, 73, 74, 75
75, 75, 76, 76, 76, 77, 77, 77, 77, 77
77, 77, 78, 78, 78, 78, 78, 79, 79, 79
80, 81, 81, 82, 82, 84, 84, 84, 85, 86

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

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.

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
