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
A person can make 100 using the digit 9 four times in an equation.<span> The equation for this math problem is: 99 + (9 / 9) = 100. This solution works because 9 divided by 9 equals 1, and 99 plus 1 equals 100</span>

Step-by-step explanation:
Total number of bulbs = 64
Number of defective bulbs = 10
Number of good bulbs = 64 - 10 = 54
P(5 good bulbs) = (54/64)⁵ = (27/32)⁵ = 0.428
Answer: 0.428
