Here let we consider the distribution is of normal with mean 500 and standard deviation 100.
Then the critical value for 5% level of significance is given by R code which is given by
qnorm(0.05,500,100)
The Output is as follows :
335.5146
The the required raw score value is 335.5146

The Student's t distribution table gives critical values for the Student's t distribution. Use an appropriate d.f. as the row header. For a right-tailed test, the column header is the value of α found in the one-tail area row. For a left-tailed test, the column header is the value of α found in the one-tail area row, but you must change the sign of the critical value t to −t. For a two-tailed test, the column header is the value...

The alternate hypothesis is a statement that the value of a population parameter (such as proportion, mean, or standard deviation) is equal to some claimed value. True O False A Uniform probability distribution is applicable to the scenarios where the set of possible outcomes can take on values in a continuous range (e.g. real numbers), such as the temperature on a given day."
