Statistics and probability

STATISTICS AND PROBABILITY QUARTER 4 FIRST SUMMATIVE TEST (TEST OF HYPOTHESIS PART 1) TRUE OR FALSE Write T if the statement is true and F if the statement is false on the space provided before each number. 1. Null Hypothesis is a claim that denotes "presence" such as presence of difference. Presence of relationship, or inequality to a certain value. 2. A Hypothesis is a claim, guess, assumption, or conjecture about a population. It is the starting point of investigation. 3. Type 2 error occurs when we accept the null hypothesis but it is false. 4. A statistical hypothesis is a claim or a conjecture that may either be true or false. 5. The alternative hypothesis of the null hypothesis that uses "equal to" is "is not equal to. 6. A test hypothesis is a series of steps used in assessing the validity of the statement. 7. A rejection region refers to the region under the normal curve where the value of the test statistic lies for which the null hypothesis will be rejected. This region is sometimes called the critical region. 8. The confidence coefficients are also called as critical values. 9. a (alpha) is the Greek symbol used to denote type 1 error. 10. Acceptance area refers to the region under the normal curve where the value of the test statistic lies for which the null hypothesis will not be rejected. 11. The significance level a 0.05 is equal to the confidence level of 95%. 12. The critical value of one-tailed given the confidence level is 97% is 1.88. 13. The critical value of one-tailed given the confidence level is 99% is 2.33. 14. The critical value of two-tailed given the confidence level is 90% is 1.64. 15. The critical value of two-tailed given the confidence level is 95% is 1.96
