Tutorial 18-Hypothesis Testing And Statistical Analysis Using T Test

Рет қаралды 36,337

A t test is a statistical test that is used to compare the means of two groups. It is often used in hypothesis testing to determine whether a process or treatment actually has an effect on the population of interest, or whether two groups are different from one another.

Acceptance range will be - 1.311 to 1.311 T value will be same as 10.96. So Reject the null hypothesis

@mahalaxmiindapure8961 6 ай бұрын

for Confidence Interval = 80 , Answer ----decision boundary between -1.311 and + 1.311, t-score= 10.96 therefore we reject null hypothesis

range is from -1.311 to 1.311 , t = 10.96 hence we reject the null hypothesis and the result of medicine is +ve on the people.

@ashishvinod2193 8 ай бұрын

T table value = 1.311 and our T test calculated value remains as it is 10.96.. T test calculated value > t table value so reject the null hypothesis and this medicine increase the IQ people..

the standard deviation given was for the sample not for the population so we could have directly used it instead of dividing it by sqrt(n). Can anyone please explain??

@sumitkoshti1171 4 ай бұрын

Mue = 100 X = 140 n = 30 CI = 80% Sample standard deviation s = 20 1. Hypothesis H0 : Mue equal to 100, H1 : Mue not equal to 100 2. Let's find significance value alfa, alfa = 1-CI alfa= 1-0.8 alfa = 0.2 or 20% 3. Let's find decision boundary, as it's two tailed test, Alfa = 0.2 And degree of Freedom = n-1 = 30-1 = 29 So, For Alfa = 0.2 and Dof = 29 the Decision boundary from T able is +-1.311 Decision Rule : If T-test value is less than -1.311 or greater than +1.311 then we reject the null hypothesis. 4. Now calculate T test value T = X-mue/s/under root n T = 10.95 5. Conclusion : As t-test value 10.95 is greater than 1.311, We reject the null hypothesis which means that medication gives us positive impact and helps to gain intelligence.

@user-vb5hh7rw3s 10 ай бұрын

decision boundary is coming 1.645 to right and -1.645 to left and t value is same as before so we should reject null hypothesis

@rohitrohit6883 10 ай бұрын

according to me if C.I. = 80% then our conclusion Reject Null Hypothesis. (t value=10.96) which is greater than boundary value i.e , +1.311
