A person's blood pressure is monitored by taking 8 readings daily. The probability distribution of his reading had a mean of 129 and a standard deviation of 7. a. Each observation behaves as a random sample. Find the mean and the standard deviation of the sampling distribution of the sample mean for the eight observations each day. b. Suppose that the probability distribution of his blood pressure reading is normal. What is the shape of the sampling distribution? c. Refer to (b). Find the probability that the sample mean exceeds 140.

a)

b) If the distribution is normal then the sampling distribution would be bell shaped and normal

c)

And we can use the z score formula given by:

And replacing we got:

And then we can find the probability using the complement rule and the normal standard distribution or excel and we got:

Step-by-step explanation:

For this case we have the following info:

represent the sample size

the sample mean

the standard deviation

Part a

If we assume that the distirbution is bell shaped then we can find the parameters like this:

Part b

If the distribution is normal then the sampling distribution would be bell shaped and normal

Part c

We want this probability:

And we can use the z score formula given by:

And replacing we got:

And then we can find the probability using the complement rule and the normal standard distribution or excel and we got:

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

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.
