You need to subtract the bonus points form the final score: 91-4=87
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
A) 120 / 2 = 60°
B) 180 - 90  60 = 30°
C) 60° same as arc length GE in part A above
D) 9 units = Rsinθ = 18sin30
 
        
             
        
        
        
We conclude  the hypothesis test as Alternative Hypothesis if the data would be very unusual if the original assumption about our parameter were correct.
- A hypothesis in statistics is a claim or supposition on the properties of one or more variables in one or more populations. There are two hypothesis to choose between because a statement might either be true or wrong.
- The null hypothesis is the assertion that we (or someone else) consider to be true. Our hypothesis test will come to one of two conclusions: "reject H0" or "do not reject H0." Remember that until data provide evidence to the contrary, we always proceed under the null hypothesis.
- If the null hypothesis is incorrect, the alternative hypothesis must be true. The hypothesis test can be different in one of three ways: greater than, smaller than, or just different (not equal). As a result, there will always be an inequality requirement in the notation for H.
