He randomly selects 12 students whose teachers reprimand in private and 12 students whose teachers reprimand in public. At the end of the year he determines the number of misbehaviors for each student. For the public condition and mean=7.7 and s=4.1 for the private condition mean=4.2 and s=3.5.

K A poll was conducted to investigate opinions about global warming. The respondents who answered yes when asked if there is solid evidence that the earth is getting warmer were then asked to select a cause of global warming. The results are given in the accompanying data table. Use a 0.01 significance level to test the claim that the sex of the respondent is independent of the choice for the cause of global warming. Do men and women appear to agree, or is there a substantial difference? 75 01 51 16 84 31 37 90 80 Male Female Click here to view the chi-square distribution table. 00 47 Human activity Natural patterns Don't know 58 56 Ho: H₁: 321 298 Identify the null and alternative hypotheses.

Use the table to answer the question.   Has a Cell Phone  Does Not Have a Cell Phone Totals Has a Computer 44 176 220 Does Not Have a Computer 26 104 130 Totals 70 280 350 The table above gives a summary of survey data asking respondents if they owned a computer or a cell phone. Is there an association between owning a computer and owning a cell phone? Explain, rounding your answer to the nearest whole percent as necessary.     There is an association since the conditional relative frequencies of owning a cell phone are 20% for those who own computers and those who do not.   There is not an association since the conditional relative frequencies of owning a cell phone are 20% for those who own computers and those who do not.   There is not an association since the conditional relative frequency of owning a cell phone is 63% for those who own computers and 37% for those who do not.   There is an association since the conditional relative frequency of…
