Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

Based on a sample of 150 textbooks at the store, you find an average of 101.49 and a standard
deviation of 17.
The point estimate is:
(to 3 decimals)
The 99 % confidence interval (use z*) is:
to
(to
3 decimals)
Based on this we:
O Reject the null hypothesis
O Fail to reject the null hypothesis

Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC
bookstore costs $ 93.29. You want to test this claim.
The null and alternative hypothesis in symbols would be:
О Но:р< 93.29
H1:p > 93.29
O Ho:µ > 93.29
H1:µ < 93.29
Ho:p = 93.29
H1:p + 93.29
О Но:р > 93.29
H:р < 93.29
O Ho: µ = 93.29
H1:µ + 93.29
O Ho: µ < 93.29
H1:µ > 93.29
The null hypothesis in words would be:
O The average price of all textbooks from the store is $ 93.29
O The average price of textbooks in a sample is $ 93.29
O The average of price of all textbooks from the store is greater than $ 93.29.
O The average of price of all textbooks from the store is less than $ 93.29.
O The proportion of all textbooks from the store that are less than 93.29 is equal to 50%
