Suppose first median, Subtracting 1.20% from every value of data does not change the order of data vales. Therefore the median would also be decrease by 1.20%. Therefore the new median would be $2.85\mathrm{\%}-1.20\mathrm{\%}=1.65\mathrm{\%}$ .

Now taking the standard deviation, Mean decreases by 1.20% and every value also decreases by 1.20% so deviation would not change. Therefore standard deviation remains unchanged.

Therefore, new standard deviation is 1.4%.

Lower and upper quartile both decrease by 1.20% when every value of data decreases by 1.20% so IQR remains would be unchanged. Therefore new IQR is equal to 1.1%.

If I have the following Hypothese:

H1: Women tend to watch romantic films more than men

Apparently it's a chi-square because I'm measuring relationships between expected frequency and Observed frequency and also because Gender is on the nominal level. But what if this is designed for a survey in which questions are on the nominal, Ordinal and interval level (Likert scale - differential sementic) will the outcome still be a Chi-square?

Use the sample data to construct a scatterplot.

Use the first variable for the x-axis. Based on the scatterplot, what do you conclude about a linear correlation?

A population has a mean of 24.8 and a standard deviation of 4.2. If ${x}_{i}=19$ , what is the z-value?

3% of the population has disease X.

A laboratory blood test has

(a) 96% effective at detecting disease X, given that the person actually has it.

(b) 1% “false positive” rate. i.e, a person who does not have disease X has a probability of 0.01 of obtaining a test result implying they have the disease.

What is the probability a person has the disease given that the test result is positive?

Do piano lessons improve the spatial-temporal reasoning of preschool children? A study designed to investigate this question measured the spatial-temporal reasoning of a random sample of 34 preschool children before and after 6 months of piano lessons. The differences (After - Before) in the reasoning scores have mean 3.618 and standard deviation 3.055.

Explain how the chi-square tests differ from parametric tests (such as t tests or ANOVA) with respect to the hypotheses, the data, and the assumptions underlying the test.
