The number of Dippin' Dots in a 5oz cup of is normally distributed with a mean of 2000 dots. A sample of 10 cups served at a Dippin' Dots food truck produced the following dot quantities: 1991 2003 2024 1995 1987 2035 2021 2017 2006 2027 Use this data with ? = 0.05 to test the claim that the food truck is serving customers too many or too few dots in each 5oz cup.

Question
The number of Dippin' Dots in a 5oz cup of is
| 1991 2003 2024 1995 1987 |
| 2035 2021 2017 2006 2027 |
Use this data with ? = 0.05 to test the claim that the food truck is serving customers too many or too few dots in each 5oz cup.
(a) Which distribution is appropriate to use here? ---Select--- chi-square distribution Student's t distribution standard normal distribution
(b) What type of test is necessary? ---Select--- left-tailed right-tailed two-tailed
(c) The sample test statistic is (round to two decimal places)
(d) The P-value is (round to three decimal places)
(e) We ---Select--- reject fail to reject the null hypothesis, and conclude that at the ---Select--- 1% 2% 5% level of significance, there is ---Select--- sufficient insufficient evidence to conclude that some number other than 2000 dots are being served in each cup.
