True , the null hypothesis of zero difference between the two population means cannot be rejected at a 0.10 level of significance.
Given :
f a 90% confidence interval for the difference in the two population means contains zero, then the null hypothesis of zero difference between the two population means cannot be rejected at a 0.10 level of significance.
at 10 % significance:
z score = 1.282
at 90 % confidence interval :
z score = 1.645
differences between population mean = 1.282
so true the null hypothesis of zero difference between the two population means cannot be rejected at a 0.10 level of significance.
