Question

For each of the following situations, find the critical value(s) for z or t. a) Ho: u = 110 vs. Ha: u# 110 at a = 0.05; n = 51 b) Ho: p = 0.05 vs. Ha:p>0.05 at a = 0.05 c) Ho: p = 0.3 vs. Ha:p*0.3 at a = 0.10 d) Ho: p = 0.5 vs. Ha:p<0.5 at a = 0.10; n = 550 e) Ho: p = 0.9 vs. Ha: p<0.9 at a = 0.10 a) The critical value(s) is(are) (Round to two decimal places as needed. Use a comma to separate answers as needed.) -0. b) The critical value(s) is(are) (Round to two decimal places as needed. Use a comma to separate answers as needed.) c) The critical value(s) is(are) (Round to two decimal places as needed. Use a comma to separate answers as needed.) d) The critical value(s) is(are) (Round to two decimal places as needed. Use a comma to separate answers as needed.) e) The critical value(s) is(are) (Round to two decimal places Use a comma to separate answers as needed.) t* z*
very stuck pls help!

Answer 1

An 1) a) Ho! M=110. vs MAIM & 110 at 2=0.05 n=51 since sample size is large. (2730). and this is a two-sided test (die. HAM #110) critical value are z* = #.96 at & 20.05. b) Hoop20.05 wis HAIP >0.05 at a=0.05 this is tailed since right (ee. Hai P>0.05)
