Question 20 2.5 pts In tests of significance about an unknown parameter of some population, which of the following is considered strong evidence against the null hypothesis? O The value of an estimate of the unknown parameter based on a simple random sample from the population Is not equal to zero. The value of an estimate of the unknown parameter lies within 2 units of the sample value. We observe a value of an estimate of the unknown parameter based on a simple random sample from the population that is very consistent with the null hypothesis. O We observe a value of an estimate of the unknown parameter based on a simple random sample from the population that is very unlikely to occur if the null hypothesis is true. The value of an estimate of the unknown parameter based on a simple random sample from the population is equal to zero
