Answer:
a. [6.6350,7.3950]
b. ME=0.5150
Step-by-step explanation:
a. Given that n=40, and that:
The required 90% confidence interval can be calculated as:
Hence, the 90% confidence interval for the population mean cash value of this crop is [6.6350,7.3950]
b. The margin of error at 90% confidence interval is calculated as:
Hence, the margin of error is 0.5150
Answer:
Step-by-step explanation:
a. Let, p be the parameter being tested. From the sample, 38% would erase all of their personal information.
-we know that the value of probabilities are in the range [0,1]:
-Given that 38% is the true value of the claim can be symbolically expressed as p=0.5
b. The null hypothesis usually represents the true value parameter under study.
-As stated above, the true value of the parameter is 38%;
-Hence, the null hypothesis is
#Alternative hypothesis is the control value, given the value of the parameter p=0.38, the alternative hypothesis is that p has a different value other than 0.39:
Answer and explanation:
Given : Expression as
To find : Use properties of exponents to explain why it makes sense to define expression ?
Solution :
Using property of exponent,
On comparing with given expression,
Here x=16 and n=4
Hence by property it defied the expression.
