A claim is made where 15% of all people will join a club if handed a brochure about it. Of 300 people in a sample who were handed a brochure, 40 joined the club. with .05 level of significance, is there ample proof the claim is true? Explain.

Expert Solution

Solution-

we have given-

A claim is made where 15%(0.15) of all people will join a club if handed a brochure about it. Of 300(N) people in a sample who were handed a brochure, 40(X) joined the club.

For testing given claim z test is calculated after summarise data.

Test results and calculation-

above test results that the null hypothesis Ho is not rejected.

so, there is enough evidence to support the claim that where 15% of all people will join a club if handed a brochure about it.

Do left-handed people live shorter lives than right-handed people? A study of this question examined a sample of 949 death records and contacted next of kin to determine handedness. Note that there are many possible definitions of "left-handed." The researchers examined the effects of different definitions on the results of their analysis and found that their conclusions were not sensitive to the exact definition used. For the results presented here, people were defined to be right-handed if they wrote, drew,...

Q1) Last year the government made a claim that the average income of the American people was $34100 However, a sample of 25 people taken recently showed an average income of $34,665 with a standard deviation of $3200. Is the government’s estimate too low? Conduct a significance test to see if the true mean is more than the reported average by the government. Use α=0.05. (a) State the null and alternative hypothesis. (b) Calculate the test statistic. (c) Calculate the...
