Problem #5: Students with the last name of U-Z:Please review Section 11.1. Are you an impulse shopper? A survey of 800 grocery shoppers indicated that 36% of males and 42% offemales make an impulse purchase every time they shop. Assume that the survey consisted of 400 males and 400 females. Let group 1 bethe males and let group 2 be the females.a = 0.01H :, = R,Calculate the test statistic:(Round to three decimal places as needed.)Determine the critical value:(Round to three decimal places as needed.)State the Conclusion:

There is always some contention about the value of a parameter or the relationship between parameters. When parametric values are unknown we estimate them through sample values. If the sample value is exactly the same as per our contention there is no high in accepting it. And if it is far from our contention there is no reason to accept it. Any assumption about the parameter or probability function is known as hypothesis testing.Given information, First sample size n1=400 Second sample size n2=400 First sample proportion p1=0.36 Second sample proportion p2=0.42 Test statistic: zcal=p1-p2P×Q1n1+1n2=0.36-0.420.39×0.611400+1400=-0.060.0344=-1.744 Table value: Read the z-table value at 1% level of significance for two tailed test is ztab=±2.58 Conclusion: zcal>ztab we accept h0. There is no significance difference between males and females.
