Was there any outliers in it or none

If P(high) = 0.36, P(low) = 0.64, P(favorable | high) = 0.94, and P(unfavorable | low) = 0.63, then what is P(favorable)? 0.0600 0.3384 0.3600 0.5752

A watch manufacturer claims that their watches on average will neither gain nor lose time during a week. A sample of 18 watches provided the following gain (+) or losses (-) in seconds per week. -0.61 -0.37 -0.38 -0.32 +0.32 -0.23 -0.20 -0.68 -0.10 -0.20 -0.38 -0.48 -0.47 -0.64 -0.04 +0.30 +0.25 +0.05 (a)  What is the point estimate for the true average gain or losses in seconds per week of the watches produced by the manufacturer? (b)  Find the 98% confidence interval for the mean gain or loss in time for the watches. (c)  Test, at the 0.02 level of significance, whether the mean gain or loss in time for the watches is 0. Is the manufacturer’s claim correct? (d)  Compute the p-value for the test in (c). (e)  State the assumption for the test in (c). (f)  Are the results of (b) and (c) consistent?

) A recent poll surveyed 1587 adults (18 years of age and older, residing in the contiguous United States, contacted by phone from randomly selected homes). Residents who agreed to participate were categorized according to their political party preference (Democrat, Republican or other) and their gender (male or female).  To make life easier, we’ll focus on the responses from the south (37% of the sample or 588 people).  Our question is about the “Gender Gap” in American politics (the gender gap is described as differences in voting preferences for men and women).  Is voting preference independent of gender?   What test should you use and why?

In a recent study,  50  males used a new weight-loss supplement, and all but  15  of them experienced weight loss after two weeks. In the same study,  100  females used the same supplement, and all but  22  of them experienced weight loss after two weeks. Fill in the blanks below to make the most reasonable statement possible.   The new weight-loss supplement was less effective on ▼(Choose one) in the study. That is because only  %  of them lost weight after two weeks, whereas  %  of the ▼(Choose one) lost weight after two weeks.

If the 5-number summary is 3, 7, 10, 11, 15, the IQR is 11-7=4.  1.5IQR = 1.5*4 = 6 Lower fence = Q1-1.5IQR = 7-6 = 1, so values less than 1 and values greater than the upper fence are considered as outliers.  What is the upper fence? Upper fence = Q3+1.5IQR = ?

can you help with 4.4.4 please

Suppose a realtor wants to determine the current percentage of customers who have a family of five or more.

Can you please explain and help me do this since I am allowed to on a ti84? Thank you. ex:You are testing the claim that the proportion of men who own cats is larger than the proportion of women who own cats.You sample 90 men, and 20% own cats.You sample 170 women, and 90% own cats.Find the proportion of the pooled samples, (pcpc), as a decimal, rounded to two decimal places.

Suppose a survey of USA Registered voters was taken to see their beliefs about extra-terrestial life.   In other words whether or not people believed that life existed on other planets in our universe.    The results are tabulated below according to party affiliation:   Test the claim  using a signficance level of 0.05, that belief in life exisiting on other planets is equally distributed among the different political parties.     Party  Believe in Life on Other Planets Democrat 20 Republican 45 Independent 34                                                                   Total = 99 a)  The type of test for this Goodness of Fit Test is B)  Critical value:  X2 c)   Test Statistic X2 d)  Decision: e)  Conclusion:
