Jennifer cantu, vp of customer services at tri-state auto insurance, inc., monitors the claims processing time of the claims division. her standard includes "a mean processing time of 5 days or less." each week, her staff checks for compliance by analyzing a random sample of 60 claims. jennifer's null hypothesis is

Null hypothesis = 5 days

Step-by-step explanation:

The null hypothesis attempts to show that no

variation exists between variables or that a single

variable is no different than its mean. It is

assumed to be true until statistical evidence

nullifies it for an alternative hypothesis.

Therefore null hypothesis equal to the mean of the variable.

The variable here is the claim processing time t

And the mean of the variable is 5 days.

Hence,

Null hypothesis = 5 days.
