Answer to Problem 47UP

False.

Explanation of Solution

It is given that if the null hypothesis is rejected then there is a causal relationship between the two categorical variables.

In chi-square test of independence the hypotheses are given below:

H0: The two variables are independent to each other.

Ha: The two variables are dependent to each other.

Here, if the null hypothesis is rejected then it can be said that the two variables are dependent.

If in a relationship, the occurrence of the 1st variable causes the 2nd variable, it can be said that there is a causal relationship between the two variables.

Therefore, it is clear that if two variables are dependent, that does not imply about causal relationship between the two variables.

Therefore, the statement is false.

4.96 The  breaking  strengths  for  1-foot-square  samples  of  a  particular  synthetic  fabric  are  approximately  normally  distributed  with  a  mean  of  2,250  pounds  per  square  inch  (psi)  and  a  standard deviation of 10.2 psi. Find the probability of selecting a  1-foot-square sample of material at random that on testing would have a breaking strength in excess of 2,265 psi.4.97 Refer to Exercise 4.96. Suppose that a new synthetic fabric has been developed that may have a different mean breaking strength. A random sample of 15  1-foot sections is obtained, and each section is tested for breaking strength. If we assume that the population standard deviation for the new fabric is identical to that for the old fabric, describe the sampling distribution forybased on random samples of 15  1-foot sections of new fabric
