Question about chi-square goodness of fit test

[Deleted member 4993]

Null hypothesis, is in my case --> It the coin is fair or not fair?
Alternate hyptothesis --> anything else?

My conclusion: 49 is greater than 3,841. the null hypothesis must be rejected.

Null hypothesis, is in my case --> It the coin is fair or not fair? ← That is a question - not a statement.

You still did not explicitly state your null hypothesis.

The coin is fair.
