A town believes the average street light is 14 ft tall. A new townsperson thinks that is not correct. 12 lights are measured, and the numbers are recorded as follows:| 13 | 14 | 12 | 16 ||----|----|----|----|| 16 | 13 | 15 | 13 || 15 | 16 | 14 | 13 |Find each for a 91% level:- **This is** [ ] A = Left-Tailed B = Right-Tailed C = 2-tailed- **Critical value(s) are** [ ] (separate with a comma if there are two)- **Test statistic is** [ ]- **p-value is** [ ]- **Where does the test statistic fall on the graph** [ ] (Left, Center, Right)

Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous fortrout. Suppose that a friend tells you that the average length of trout caught in PyramidLake is μ = 20 inches. However, the Creel survey reported that for a random sample of 27fish caught, the mean length was 22.1 inches with a sample standard deviation of 4.3inches. Does this data indicate that the average length of trout caught at Pyramid Lake ismore than 20 inches? Use α = 0.05.a.

The IQR (interquartile range) is the difference between Q3 and Q1. For the data below (same data as in previous questioni find the IQR: IQR- A value is considered unusually small if it is 1.5 IQR smaller then the median and is considered unusually large if it is 15 1QR larger then the median. Based on this, what is the smallest usual value for the data set? (do not round, type as a decimal What is the largest usual value for the data set? (do not round, type as a decimal) An outlier would be a data value which is smaller then the smallest unual data value or larger then the largest data value. If there is an outier, type the value of the authier below. Otherwise type N. Data set:

Solve question 5. Show work for it aswell please with the steps.
In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.The artifact frequency for an excavation of a kiva in Bandelier National Monument gave the following information.
