Ummm we can't answer that question if there isn't a question , but if you are bored I understand why you put that ^-^
Using the <u>normal distribution and the central limit theorem</u>, it is found that there is a 0.0409 = 4.09% probability that, from a simple random sample of 300 adults in the county, less than 50% would say they believe that gardening should be part of the school curriculum.
In a normal distribution with mean
and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample proportions for a proportion p in a sample of size n has

In this problem:
- The proportion is of 55%, hence

- The sample has 300 adults, hence

Then, the <u>mean and the standard error</u> are given by:


The probability is the <u>p-value of Z when X = 0.5,</u> hence:

By the Central Limit Theorem



has a p-value of 0.0409.
0.0409 = 4.09% probability that, from a simple random sample of 300 adults in the county, less than 50% would say they believe that gardening should be part of the school curriculum.

Answer:
x^2 +4x -4
Step-by-step explanation:
f(x) = 4x+1
g(x) = x^2 - 5
f(x) + g(x) = 4x+1 + x^2 -5
= x^2 +4x -4
Answer:
Step-by-step explanation:
there is 8x3=24 and 12x2=24 and there is 6x4=24 and there is 1x24
there is 1x32 16x2 8x4
Simply take the number and subtract it from 90 for the complement and 180 for the supplement
