The Scottsdale fire department aims to respond to fire calls in 7 minutes or less, on average. Response times are normally distributed with a standard deviation of 1 minute 42 seconds. would a sample of 18 fire calls with a mean response time of 7 minutes 22 seconds provide sufficient evidence to show that the goal is not being met at a=.01? choose the appropriate hypothesis a)H0:µ≤ 7 min vsH1:µ> 7 min, Reject Hθ if zcalc> 2.326 b)H0:µ≥ 7 min vsH1:µ< 7 min, Reject Hθ if z calc> 2.326 c) Use Excel to find the p-value.(round your answer to 4 decimal places).?
