Answer:
Decision rule
Reject null hypothesis
Conclusion
There is significance evidence that the true mean is different from 0.86
Step-by-step explanation:
From the question we are told that
The population mean 
The sample is mean is 
The standard deviation is 
The level of significance is 
The sample size n = 3
The null hypothesis is 
The alternative hypothesis is 
Generally the test statistics is mathematically represented as

=> 
=>
Generally p- value is mathematically represented as

From the z-table

So

=> 
From the obtained question we see that
Hence we reject the null hypothesis
Answer:

Step-by-step explanation:
Slope is equal to the change in y over the change in x.

The change in x is equal to the difference in x-coordinates, and the change in y is equal to the difference in y-coordinates .

Substitute in the values of x and y into the equation to find the slope.

Simplify.

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>slope</u><u> </u><u>is</u><u> </u><u>3</u><u>/</u><u>4</u><u>.</u>
