Percentage

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Question

please answer question c.

In a rural area only about 33% of the wells that are drilled find adequate water at a depth of 100 feet or less. A local man claims to be able to find water by dowsing, that is, using a forked stick to indicate where the well should be drilled. You check
with 66 of his customers and find that 27 have wells less than 100 feet deep. Answer the questions below. Assume the independence assumption is met.
(a) Write appropriate hypotheses.
Họ:
The percentage of successful wells drilled by the dowser is equal to 33%.
HA:
The percentage of successful wells drilled by the dowser is greater than 33%.
(b) Check the necessary assumptions.
The independence assumption is satisfied.
The randomization condition is not satisfied.
The 10% condition is satisfied.
The success/failure condition is satisfied.
(c) Perform the mechanics of the test. What is the P-value?
P-value =
(Round to three decimal places as needed.)
