A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 409 gram setting. It is believed that the machine is overfilling the bags. A 20 bag sample had a mean of 413 grams with a standard deviation of 11. Assume the population is normally distributed. Is there sufficient evidence at the 0.1 level that the bags are overfilled? Step 2 of 6: Find the value of the test statistic. Round your answer to three decimal places.

Answer:Given:The hypothesized mean $(\mu) = 409$The sample mean $(\overline{x}) = 413$The sample standard deviation $(s) = 11$The sample size $(n) = 20$ The significance level $(\alpha) = 0.1$ Solution:The null and alternative hypothesis: $H_0: \mu = 409$$H_a: \mu > 409$…
