One-Sample t Hypothesis Testing
A researcher was interested in whether the graduate students enrolled in American stats classes have a different IQ than graduate students in British stats classes. It is known that the population’s mean IQ of students in American stats classes is 98. The researcher obtained a random sample of 6 British graduate students and asked them their IQ. These data appear in the table below.

In given hypothesis problem we set the hypothesis
such as
Null hypothesis : The graduate students stats class in America and graduate students stats class in British have same IQ
vs Alternative hypothesis : The graduate students stats class in America and graduate stats class in students British have different IQ
Final Answes: we fail to reject null hypothesis
so we conclude that they Both have same IQ

Independent samples t-test A researcher was interested in whether the best 5K running time of female graduate students is lower than male graduate students. The researcher obtained a random sample of 8 male and 8 female graduate students and gathered their best 5K running times. These scores appear in the table below. Female 5K run time (min) Male 5K run time (min) 35,10 26,10 37,20 21,10 26,40 17,50 23,50 31,10 32,10 28,15 28,59 27,65 27,10 22,10 27,30 23,56

1. A college admissions director wishes to estimate the mean age of all students currently enrolled. In a random sample of 81 students, the mean age is found to be 20.51 years. From past studies, the standard deviation of the population is known to be 2 years, and the population is normally distributed. Construct a 99% confidence interval of the population mean age.
