Given:
The function is:
To find:
The initial value of the function.
Solution:
We have,
The value of the function at x=0 is called the initial value of the function.
For x=0, we get
Clearly 0.88 is a non zero number and zero to the power of a non zero number is always 1.
Therefore, the initial value of the function is 350.
Answer:
Step-by-step explanation:
Given that n =30, x bar = 375 and sigma = 81
Normal distribution is assumed and population std dev is known
Hence z critical values can be used.
For 95% Z critical=1.96
Margin of error =
Confidence interval = 375±29
=(346,404)
B) 99% confidence
Margin of error = 2.59*Std error =38
Confidence interval = 375±38
=(337, 413)
C) For 90%
Margin of error = 20
Std error = 20/1.645 = 12.158
Sample size
Atleast 44 people should be sample size.
