A marketing researcher wants to estimate the mean amount spent ($) on Amazon. com by Amazon Prime member shoppers. Suppose a random sample of 100 Amazon Prime member shoppers who recently made a purchase on Amazon. com yielded a mean amount spent of $1,500 and a standard deviation of $200. Is there evidence that the population mean amount spent on Amazon. com by Prime member shoppers is different from $1,475? (Use a 5% level of significance.) Also, suppose that the p-value is 0.2142.
A: We fail to reject the null hypothesis since t-stat = 1.25 is smaller than the critical value = 1.98.
B: We fail to reject the null hypothesis since the provided p-value < 0.05.
C: Both B & C
D: We reject the null hypothesis since the t-stat = 1.25 is less than the critical value 2.01
