Aresearcher in a small midwestern town wants to estimate the mean weekday sleep time of its adult residents. he takes a random sample of 40 adult residents and records their weekday average sleep time as 6.4 hours. the researcher knows that the population standard deviation is 1.8 hours.
what is the lower confidence limit (lcl) of the 95% confidence interval for the mean weekday sleep time of all adult residents of this midwestern town? round your answer to 2 decimal places.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

whatvare the choices

step-by-step explanation:

answer: options

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
