The price of a certain electronic product at a chain store is 180 TL. The same electronic product is also available through various online stores and five of the store prices are as follows: 155, 179, 175, 175, 161 TL. Let’s assume that online prices are normally distributed and at the significance level ? = 0.1.
Given the information above, what can we conclude about the mean online store price of the product?
|
The average price of the product at online stores is less than 180 TL. |
|
The average price of the product at online stores is more than 180 TL. |
|
The average price of the product at online stores is 180 TL. |
|
The average price of the product at online stores is 175 TL. |
|
The average price of the product at online stores is 171 TL. |
Since the test statistic value t = – 1.367 < – 1.533 the test statistic falls in to the rejection area of the null hypothesis. Therefore, we reject the null hypothesis H0 : µ = 180 at the level of significance ? = 0.1. In conclusion, we conclude that the average price of the product at online stores is less than 180 TL at the significance level ? = 0.1.
