    Sir, for the ques on one tailed test, you mentioned that 1.80 doesn't lie between -1.64 to +1.64. So, the null hypothesis is rejected. Since it is a one tailed test, why are considering this range of -1.64 to +1.64?

    very well explained. very clear about null hypothesis. Z is playing key role. once going out of confidence is no confidence so the null hypothesis is rejected.

    Sir, p value badhane se confidence interval kam ho rha hai. 90% confidence level pe Ho: 58 is significantly equal to 60, wrong hoga. Par 95 % confidence level pe sahi hoga. Iska ye matlab hua ki confidence level badhane se hum error ki tolerance ko increase kar rhe hain. Kya meri understanding sahi hai ?

    2 communities. The respondent in each house was
    asked whether or not anyone in the house was
    bothered by air pollution. The responses are
    tabulated below (Given x2 (0.05) = 3.841) :
