Answer:
Step-by-step explanation:
From the given information;
The null hypothesis & alternative hypothesis:
The test statistics can be computed as:
The p-value = 2(Z > 2.11) since this is a two-tailed test
The p-value = 2( 1 - Z < 2.11)
The p-value = 2 (1 -0.9826)
The p-value = 2 (0.0174)
The p-value = 0.0348
Decision Rule: To reject the 
if the p-value is less than
Conclusion: We fail to reject and conclude that the population mean = 2, thus the machine is properly adjusted.
Answer:
3,000,000,000
Step-by-step explanation:
3 x 10^9 = 3 x 1,000,000,000 because if it were 10^1, then there would be 1 zero. Same thing for this. Since it's 10^9, there will be 9 zeroes.
12 over 19 worked it out percentage wise and got 63.15 and many more number after. Hope thts the answer u were looking for also 50/50 chance of getting a tails thts the more accurate answer I'd say now
