Answer:
P-value = 0.2177
Conclusion: The P-value 0.2177 is greater than the significance level 0.05, so we fail to reject the null hypothesis (P = 3/5)
Step-by-step explanation:
Null hypothesis (Ha): P = 3/5
Significance level = 0.05
Decision rule: Reject Ha if the P-value and is less than or equal to the significance level. Fail to reject Ha if P-value is greater than the significance level
Using the standard normal distribution table, the critical value of the test statistic z = 0.78 is 0.7823
P-value = 1 - 0.7823 = 0.2177
The P-value is greater than the significance level, so we fail to reject the null hypothesis (P = 3/5)
Answer:
x = 5/8 for 5x - 3 = (1/5)x
Step-by-step explanation:
To find x, we want to isolate our 3 from our x-values. You can add three to both sides of the equation and get it to the other side and then subtract 1/5x from 5x.
(5x - 3) + 3 = ((1/5)x) + 3
5x = (1/5)x + 3
5x = (25/5)x
((25/5)x) - (1/5)x = ((1/5)x + 3) - (1/5)x
(24/5)x = 3
From here, you would want to solve for x. This would mean multiplying 3 by 5 and dividing your product by 24.
5*3 = 15
15/24 = 5/8 = x
Hope this helps!
