Mrs. eaton's class is participating in the "box tops for education" campaign. on the first day, her
class collected 2 tops. on the third day, her class collected 8 tops. let d represent each collection
day and n represent the number of tops collected on that day.
based on the situation, john claims the number of tops collected can be modeled by an exponential
function. riley disagrees and claims the number of tops can be modeled with a linear function. what
is the number of tops collected on the sixth day based on the exponential model? what is the
number of tops collected on the sixth day based on the linear model?

Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 6767 type i ovens has a mean repair cost of $79.79$⁢79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$⁢19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$⁢75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$⁢21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let μ1μ1 be the true mean repair cost for type i ovens and μ2μ2 be the true mean repair cost for type ii ovens. step 2 of 4 : compute the value of the test statistic. round your answer to two decimal places.
