Pls helppp anyone pls

Given:

Mean = 45

Standard deviation = 9

Confidence level = 95%.

To find:

The confidence interval.

Solution:

The formula for confidence interval is:

Where, is mean, z is the z-value at given level of confidence, is the standard deviation and n is the number of observations.

The z-value at 95% confidence level is 1.96.

Here number of observations are not given. Assume it is 1.

Putting .

It can be written as

Approximate the value to the nearest whole number.

The interval for the middle 95% of snowfall is  27 to 63.

Therefore, the correct option is A.

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.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
