The hypothesis that more people would choose the number 7 as their 'lucky' number than any other number can be tested with a one-variable chi-square test, as it involves comparing the frequencies of one variable (people's choice of 'lucky' number). The other hypotheses involve comparing two variables (choice of 'lucky' number and level of superstition), which would require a different type of statistical test.
