A shock bolt follows a poison curve with an ability to perform 7 shocks every 10 min what are the odds of a random shock bolt be

Serhud [2]

0% chance because there can only be 7 shocks per 10 minutes. Or 7*3 shocks per 10*3 minutes (21 per 30), so it is impossible.

Answer:

The smallest sample size to satisfy the conditions is n=500.

Step-by-step explanation:

The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

$np\geq10\\\\n(1-p)\geq10$

The largest sample size required will be for the minimum p or (1-p).

This happens to be the proportion that can play other instruments: 2%.

Then, we can calculate the minimum sample size as:

$np\geq10\\\\n(0.02)\geq10\\\\n\geq(10/0.02)\\\\n\geq500$
