A company claimed that every18-ounce bag of their chocolate chip cookies contained at least 1000 chocolate chips. Dedicated statistics students at a school purchased some randomly selected bags of cookies and counted the chocolate chips. Some of their data are given below.

a) The independence condition is plausibly

satisfied and the Nearly Normal Condition is plausibly

satisfied.Therefore, using theStudent-t model for inference should be

reliable.

b) Create an appropriate hypotheses for the test.

H0: mu equals 1000

=1000

HA: mu greater than 1000

>1000

The test statistic is t=

nothing

(Round to two decimal places asneeded.)

TheP-value is

(Round to three decimal places asneeded.)

State your conclusion. Use =0.05.
