Topic : Rejection Region for a Given Level of Significance

GENERAL INSTRUCTION: Write your answer on a separate paper Activity 1: Suppose that the z is the test statistic for hypothesis testing, calculate the value of z for each of the following 1.p=10,a=3,n=68,and)f=9.2 2.p=26,a=4.5,n=30,and)?=28.3 3.p=75,a=5.8,n=118,andf=72.2 4._u=52,a=7,n=160,and)7=49.6 5.y=100.o=12.n=130.and)?=92 Activity 2: Calculate the tstatistic for each of the following 1.p=12,X'=15,s=4.n=12 2._u=10,1?=7.8,s=5.1,n=10 3.y=5.3,,\\_'=5.s=0.14,n=8 4.y=9.1,f=7.2,5=1.3,n=15 5._u=7,)?=5,s=3,n=10 Activity 3: For each of the following, sketch the normal curve and shade the area of the rejection region. 1. n =12,a = 0.05, left-tailed 2 n =10,a = 0.05. right-tailed 3. n = 3. a = 0.05. left-tailed 4. n = 15. a: = 0.05, right-tailed 5. n =10,a = 0.05, two-tailed Activity 4: For each of the following, sketch the normal curve and shade the area of the rejection region. 1. z > 1.96 2. z>1.645 3. z1.645 5. z 2.58 23 Activity 5: For each of the given, sketch the normal curve and shade the area of the rejection region. Identify if the z-value is in the rejection region or not 2 = 2, 95% confidence, two-tailed Z = 2.68, 95% condence, two-tailed Z = 1, 95% confidence, right-tailed Z = 1.33, 99% condence, two-tailed Z = 4, 99% condence, twotailed 9:59P."
