Answer #1

a)

Ho :   µd=   0
Ha :   µd >   0

b)

Level of Significance ,    α =    0.05                  
                          
sample size ,    n =    15                  
                             
                          
mean of difference ,    D̅ =    1.1500                  
                          
std dev of difference , Sd =        1.6400                  
                          
std error , SE = Sd / √n =    1.6400   / √   15   =   0.4234      
                          
t-statistic = (D̅ - µd)/SE = (   1.15   -   0   ) /    0.4234   =   2.72
                          
Degree of freedom, DF=   n - 1 =    14                  
t-critical value , t* =        1.76 [excel function: =t.inv(α,df) ]              

O A. Reject Ho. There is sufficient evidence at the a = 0.05 level of significance to conclude that the difference is greater

c)

o B. There is sufficient evidence that babies may have the ability to assess surprising behavior. Further experimentation sho

  

Please let me know in case of any doubt.
