A random sample of size 15 is selected from a normal population. The population standard deviation is unknown. Assume the null h
taurus [48]

Answer:

Interval for t statistic = (-1.345, 1.345)

Step-by-step explanation:

given that a random sample of size 15 is selected from a normal population. The population standard deviation is unknown.

Since population std deviation is unknown and also sample size <30, we have to use t test only for testing of hypothesis

Given it is a two tailed test at 10% significance level.

Degree of freedom = 15-1 =14

t critical value for df 14 two tailed is

1.345

Hence our test statistic should lie between

(-1.345, 1.345)

Then null hypothesis is accepted

Other wise it is rejected.

Andreas93 [3]

Answer: hi your question is incomplete  below is the complete question

answer:

The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.

The result has a practical significance because the large difference in mean values.

Step-by-step explanation:

Sample size = 85 followed a vegetarian diet

Period =  4 months,

Mean systolic blood pressure=  124 mmHg

Sample size = 75 followed non-vegetarian diet

Period = 4 months

Mean systolic Bp = 138 mmHg
