Answer:
Log 48 base 3 on changing base is3.524 and log X base 5 on solving is290.385
Step-by-step explanation:
Given log48 base 3
To change the base to natural logarithm for easy simplification
Log M base n is equal to log M /log n
Hence log3 48= log48/log 3= 1.6821/0.4771= 3.524
Changing to base 5
Log X base 5 is 3.524
log5 X=3.524
Recall that loga b=x
a^x=b
So
5^3.524=290.385 =X

Answer:
B. Park users are more likely to be willing pay more to improve park.
Step-by-step explanation:
The sample is biased because it is only made up of people that patronize and use the park. They will be more willing to pay to improve the park because it satisfies and fulfills their needs.
This given sample is not representative of the poll as it is restricted to park users alone which are not the only tax payers in the area.
To have a more balanced representation, the whole population should be sampled irrespective of whether they are park users or not. This will give a fair representation.
Answer:
The 95% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample size is
The sample mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance is mathematically represented as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the margin of error is mathematically evaluated as
=>
=>
The 95% confidence interval is mathematically represented as
substituting values
