See sir i posted earlier too but he didn't give me complete answer and also given handwritten solution, pls i need all parts and dont do handwritten and pls explain everything and use excel formula to calculate not the statistics tables , pls follow this all i will definitely like or else pls skip A corporation randomly selects 150 salespeople and finds that 66% who have never taken a self-improvementcourse would like such a course. The firm did a similar study 10 years ago in which 60% of a random sample of 160salespeople wanted a self-improvement course. The groups are assumed to be independent random samples. Let p,and p₂represent the true proportion of workers who would like to attend a self-improvement course in the recent study and thepast study, respectively.20. Referring to that information, if the firm wanted to test whether this proportion has changed from the previous study,which represents the relevant hypotheses for two tailed?1) Ho: P₁ - P₂ -0 versus H₁: P₁ - P₂02) Ho P₁ - P₂0 versus H₁: P₁-P₂-03) Ho: P₁-P₂ S 0 versus H₁: P₁-P₂>04) H₁: P₁-P₂ 2 0 versus H₁: P₁ P₂ <05) H₁:0=o and H₁:a #a21. Referring to that information,, if the firm wanted to test whether a greater proportion of workers would currently like toattend a self-improvement course than in the past, which represents the relevant hypotheses?1) Ho: P₁ - P₂ = 0 versus H₁: P₁ P₂ 0 2) H₁ P₁ P₂ 0 versus H₁: P₁-P₂ = 03) H: P₁ - P₂ S 0 versus H: P₁-P₂> 0 4) H: P₁ - P₂20 versus H₁: P₁ - P₂ <05) H₁:0=o and H₁ :oo22. Referring to that information.. what is the unbiased point estimate for the difference between the two populationproportions?1) 0.062)0.103) 0.154)0.125) 0.2223. Referring to that information, what is/are the critical value(s) when performing a Z test on whether populationproportions are different if a= 0.05?1) £1.6452) 11.963) 12.334) £2.085) -1.9624. Referring to that information, what is the value of the test statistic to use in evaluating the alternative hypothesis thatthere is a difference in the two population proportions?1) 4.3352)1.963) 1.0934) 0.065) 0.025. Referring to that information, the company tests to determine at the 0.05 level whether the population proportion haschanged from the previous study. Which of the following is most correct?a) Reject the null hypothesis and conclude that the proportion of employees who are interested in a self-improvement course has changed over the intervening 10 years.b) Do not reject the null hypothesis and conclude that the proportion of employees who are interested in aself-improvement course has not changed over the intervening 10 years.c) Reject the null hypothesis and conclude that the proportion of employees who are interested in a self-improvement course has increased over the intervening 10 years.d) Do not reject the null hypothesis and conclude that the proportion of employees who are interested in aself-improvement course has increased over the intervening 10 years.

It is given asn1 = 150, p1^ = 66% = 0.66n2 = 160, p2^ = 60% = 0.60Note: According to Bartleby…

Select the measurement scale in the right column that best matches the description in the left column. Note that each scale (nominal scale, ordinal scale, interval scale, and ratio scale) will be used exactly once. The values of data measured on this scale can be rank ordered. In addition, the differences between two adjacent ranks are equal. The values of data measured on this scale can be a number or a name, but they can be rank ordered. The values of data measured on this scale can be rank ordered and have meaningful differences between scale points. For this scale, there is also an absolute zero point. Data on this scale are measured by determining the category to which they belong.

kindly recheck this because I posted it on my other account but I think the first answer is wrong, I trust you to recheck it properly.
Please help me detailed solution with concepts and dont do handwritten , explain each and everything if not pls skip , i will like and if not followed then viceversa. And also use Excel to find anything, dont use statistics tables.
