A nаtiоnаl retаil chain tracks the daily time‑оn‑site (in minutes) that custоmers spend browsing the store before making a purchase. The company’s historic data (all stores, all days) show a population mean of 34.5 minutes. To evaluate a recent redesign of the store layout, the analyst randomly selects 30 store‑day observations from the month after the redesign. The sample statistics are: STATISTIC VALUE Sample size ( n ) 30 Sample mean x-bar 36.2 minutes Sample standard deviation ( s ) 8.7 minutes Assuming the population standard deviation is unknown, the analyst will use a one‑sample t‑test to determine whether the redesign has increased the average time‑on‑site. Calculate the t‑statistic for this test. Report the answer to three decimal places (e.g., 0.123).
