The decision to reject or fail to reject a null hypothesis is based on computing a test statistic from sample data. The test statistic is then compared to a critical value, and if it exceeds the critical value, the null hypothesis is rejected. The level of significance is used to determine the critical value, but it is not the measure itself. The population parameter is the true value of the parameter being tested, but it is not directly computed from sample data.
