if my price is 52.00 and I am told that I am 180 percent higher. How do I find the lower value
The answer depends on the distribution. But since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
The critical value is an FINISHED
The positive critical value depends on the distribution and then the parameters (if any) which characterise the distribution.
The two tailed critical value is ±1.55
The answer will depend on whether the critical region is one-tailed or two-tailed.

z = 1.56 gives a 2-tailed interval for 88%.z = 1.56 gives a 2-tailed interval for 88%.z = 1.56 gives a 2-tailed interval for 88%.z = 1.56 gives a 2-tailed interval for 88%.
if my price is 52.00 and I am told that I am 180 percent higher. How do I find the lower value
The answer depends on whether the test is one-tailed or two-tailed.One-tailed: z = 1.28 Two-tailed: z = 1.64
For a two-tailed interval, they are -1.645 to 1.645
1.75
1.31
The answer depends on the distribution. But since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
It depends on whether the interval is one sided or two sided. The critical value for a 2-sided interval is 1.75
Z = ± 1.8119 gives a two-tailed interval of 93%
